The Best Can Openers
Most of us don’t give much thought to can openers until ours breaks or leaves us with a jagged lid and bleeding finger. But here’s the reality: Americans open an average of 83 cans per household annually, and using the wrong tool for this repetitive task can lead to hand strain, wasted food from poorly opened cans, and genuine safety hazards.
During our testing process, we discovered that the difference between a mediocre can opener and an excellent one isn’t just about convenience. It’s about whether you’ll actually use those canned tomatoes for your pasta sauce or avoid them because opening the can feels like a workout. Whether you’re dealing with arthritic hands, tiny apartment kitchens, or just want to stop fighting with your current opener, we’ve found options that make this everyday task remarkably simple.

How We Tested Can Openers
Our testing team approached this project with the same seriousness we’d bring to any essential kitchen tool. We purchased 15 different can openers across various price points and styles, from basic manual models under ten dollars to premium electric units approaching a hundred dollars.
Each opener faced an identical gauntlet of challenges. We opened standard soup cans, oversized restaurant-supply tomato cans, small tuna cans, and those annoyingly thick cans of coconut milk that seem designed to defeat lesser openers. We tested on new cans with pristine rims and dented cans that had been knocked around during shipping. We even tested how each opener performed after opening 50 consecutive cans to simulate months of regular use.
Beyond pure functionality, we evaluated several critical factors that determine real-world satisfaction. Comfort during use proved essential, especially for individuals with arthritis, limited hand strength, or conditions that affect grip. We measured the force required to operate each opener and noted any hand fatigue after extended use.
Safety was paramount in our assessment. We examined every opened can lid and rim for sharp edges, tested how easily we could remove lids without touching dangerous surfaces, and evaluated whether the openers themselves had any pinch points or sharp components that could cause injury during normal operation.
Cleaning and maintenance matter more than most people realize. A can opener that collects food residue in unreachable crevices can quickly become a hygiene problem. We ran each opener through multiple cleaning cycles, checking how easily we could remove debris and whether any components were dishwasher safe.
Durability testing went beyond the initial 50-can challenge. We examined build quality, identified potential failure points, researched common complaints from long-term users, and consulted repair data from consumer advocacy groups to understand which models actually last versus which fall apart after six months.
Best Can Openers Our Picks
The Hamilton Beach Smooth Touch Electric Automatic Can Opener emerged as our testing team’s favorite for good reason. This isn’t just about pressing a button instead of turning a crank. It’s about what happens when your mother with rheumatoid arthritis can finally open her own soup cans again without calling for help. It’s about coming home exhausted after a long day and not having to wrestle with dinner ingredients.
What genuinely impressed us during testing was how this opener handles real-world imperfections that defeat lesser models. We threw dented cans at it, those awkward small tuna tins that seem to slip out of every manual opener, and even some slightly rusty cans from the back of the pantry that we’d been avoiding for months. The Hamilton Beach handled everything without hesitation, automatically stopping when the cut was complete and releasing the lid without requiring you to touch any sharp edges.
The side-cutting mechanism represents the biggest advantage here. Instead of cutting through the top of the can like traditional openers, it cuts along the side seam. This leaves both the lid and the can rim completely smooth, with no sharp edges whatsoever. During our testing, we ran our fingers along dozens of opened can rims and never once encountered anything remotely dangerous. For households with curious children, clumsy family members, or anyone tired of band-aids from can-opening accidents, this safety feature alone justifies the investment.
But here’s what really sold us during daily use: the Hamilton Beach feels like it was designed by people who actually cook. The tall lever makes positioning cans effortless, even large restaurant-size tins. The magnetic lid holder keeps everything secure without requiring you to stabilize the can with your other hand. And when testing revealed that the knife and lever assembly detaches completely for cleaning, we finally understood why this opener doesn’t develop that gross food residue buildup that plagues so many electric models.
The build quality exceeded our expectations for the price point. The stainless steel cutting mechanism showed no dulling or degradation even after our 50-can endurance test. The cord management system keeps things tidy on your counter. And the chrome finish, while not essential to performance, gives it a premium appearance that doesn’t look cheap next to your other appliances.
This opener particularly shines for specific users and situations. Anyone dealing with arthritis, carpal tunnel, or hand injuries will find the minimal effort required transformative. Seniors maintaining independent living arrangements gain genuine peace of mind from the safety features. And busy parents juggling multiple tasks appreciate the set-it-and-forget-it operation that lets them prep dinner while simultaneously helping with homework.
The only scenario where we’d recommend looking elsewhere involves truly cramped kitchens with zero counter space and absolutely no room for a corded appliance. Even then, we’d suggest reconsidering your storage solutions before passing on this opener’s benefits.
During our testing marathon, the Canslab Ultrablade PRO Auto Stop Can Opener caught our attention for reasons that went beyond basic functionality. This opener demonstrated the kind of consistent, precise performance that serious home cooks genuinely appreciate, the type of reliability that matters when you’re trying to time multiple dishes perfectly for dinner service.
The auto-stop feature proved to be more than just a convenience gimmick. We found ourselves repeatedly impressed by how the Ultrablade PRO sensed exactly when it had completed a full rotation around the can and stopped automatically without any guesswork. This prevented the frustrating over-cutting that leaves you with torn metal fragments or the equally annoying under-cutting that forces you to finish manually with kitchen shears. Every single can we opened during testing resulted in a clean, complete cut with zero drama.
What distinguishes this opener in actual use involves the cutting precision we experienced with every type of can imaginable. Those thick-rimmed coconut milk cans that typically require multiple passes? The Ultrablade PRO powered through them on the first try. Dented cans with slightly warped rims? No problem. Even those frustratingly small cans of tomato paste that seem designed to slip out of every opener’s grip stayed secure and opened cleanly.
The ergonomics revealed thoughtful design decisions that mattered during extended use. The handle positioning requires zero awkward wrist angles, which became particularly apparent when we opened multiple cans while meal prepping for the week. The grip material provided security without creating uncomfortable pressure points. And the smooth operation meant that even team members with limited hand strength could use this opener effectively, though it does require more effort than a fully electric model.
We particularly appreciated how the Ultrablade PRO handles cleanup. Unlike some manual openers with numerous crevices that trap food particles, this design featured smooth surfaces that wiped clean easily. A quick rinse under hot water removed any residue, and occasional deeper cleaning with a bottle brush kept everything sanitary. After weeks of testing, we noticed zero rust formation or degradation in cutting performance.
This opener proves ideal for specific kitchen situations and user preferences. Home cooks who resist cluttering their counters with electric appliances but still want superior performance will find this hits the sweet spot. The manual operation means it works during power outages, travels easily, and requires no outlet proximity considerations. For vacation homes, RVs, camping setups, or simply as a reliable backup to an electric model, the Ultrablade PRO delivers professional-grade results.
The durability we observed suggests this opener will remain in your kitchen drawer for years rather than months. The solid construction and quality materials indicated none of the typical failure points we’ve seen in budget manual openers. While it costs more than basic handheld models, the performance difference became obvious within the first few uses during our testing.
The Kitchen Mama Auto Electric Can Opener redefined our understanding of what a battery-operated opener could achieve. We’ve tested numerous cordless models over the years, and most ended up disappointing us with weak motors, unreliable operation, or batteries that died after a handful of uses. The Kitchen Mama broke that pattern completely, delivering consistent performance that actually rivalled corded electric models in our testing.
The portability advantage became immediately apparent in real-world testing scenarios. We took this opener to a potluck where the host discovered she’d forgotten to open several cans for her recipes. The Kitchen Mama handled everything right there at the dining table without requiring anyone to hunt for outlets or deal with cords. During a planned power outage simulation, this was the only electric opener in our testing lineup that kept working flawlessly. And when testing in a small apartment kitchen with exactly two outlets, both perpetually occupied, the cordless design eliminated the usual appliance-juggling dance.
What genuinely impressed us was the cutting mechanism’s sophistication. Unlike the crude puncture-and-saw action of cheap battery openers, the Kitchen Mama’s blade cut smoothly and consistently around each can rim. We opened everything from tiny cat food cans to large restaurant-supply tomato tins, and the opener automatically adjusted to different can sizes without requiring any manual intervention. The safety cutting feature left remarkably smooth edges, though not quite as perfectly smooth as the Hamilton Beach’s side-cutting approach.
The one-touch operation proved delightfully simple during testing. You position the opener on the can, press the button, and it automatically grips, cuts, and releases when finished. This hands-free operation meant we could be stirring a sauce with one hand while the opener worked independently, a multitasking advantage that manual models simply cannot offer. The magnetic grip held cans securely without any wobbling or slipping, even when we deliberately tried to destabilize it during testing.
The compact, lightweight design that made this opener so portable also revealed its ideal use cases. This became our testing team’s favorite recommendation for RV enthusiasts, boat owners, and camping aficionados who want electric can opener convenience without depending on shore power or generators. College students in dorm rooms with limited kitchen access found this infinitely more practical than countertop models. And seniors with storage limitations appreciated how easily this tucked into a drawer rather than monopolizing precious counter space.
We also recognized this opener as the perfect solution for multi-level homes where your cooking sometimes happens away from the main kitchen. Preparing snacks in a basement entertainment area, opening cans in an upstairs guest suite, or managing outdoor kitchen setups all became simpler with a portable electric opener. The Kitchen Mama eliminated the old question of whether it was worth trudging to another floor just to use the can opener.
During durability testing, the Kitchen Mama demonstrated solid construction that suggested longevity. The plastic housing felt substantial rather than flimsy, the motor maintained consistent power throughout extended use, and the cutting blade showed no dulling after our 50-can challenge. While we always recommend treating battery-operated devices more carefully than their corded counterparts, this opener proved robust enough for regular daily use.
The Cuisinart CCO-50BKN Deluxe Electric Can Opener represents what happens when a respected kitchen brand applies genuine engineering expertise to a seemingly simple appliance. During our testing, this opener consistently delivered the kind of refined performance that reminded us why premium appliances command higher prices, though whether those refinements justify the cost depends entirely on your priorities and budget.
The power lever activation system proved more intuitive than we expected during testing. Instead of complicated buttons or switches, you simply press down on the lever and the opener automatically engages, punctures the can, and begins cutting. The motor demonstrated noticeably more torque than competing models, powering through even the most stubborn cans without hesitation or stalling. We deliberately tested it on severely dented cans with compromised rims, and the Cuisinart handled them all without the grinding sounds or multiple attempts that lesser openers required.
What particularly impressed our testing team was the knife’s sharpness and cutting precision. Every can we opened with the Cuisinart resulted in clean, consistent cuts with absolutely no ragged edges or incomplete sections. The removable cutting assembly maintained its effectiveness throughout our entire testing period, showing zero degradation in performance. And when we finally cleaned the cutting components, we appreciated how the entire mechanism detached with a simple twist, allowing thorough washing without any frustrating disassembly procedures.
The build quality revealed Cuisinart’s appliance expertise immediately. The housing felt substantial and stable during operation, with none of the wobbling or shifting we experienced with cheaper electric models. The stainless steel accents weren’t just cosmetic; they indicated genuine durability in high-contact areas. And the wider base provided excellent stability when opening larger, heavier cans that sometimes tipped over lesser openers during testing.
The magnetic lid holder worked flawlessly throughout our testing, securing lids of all sizes without dropping them into the can contents or onto the counter. This seemingly small feature made a real difference in actual use, particularly when dealing with messy contents like tomato sauce or pet food. We never once had to fish a lid out of the can or wipe up spills from dropped lids when using the Cuisinart.
This opener makes the most sense for specific kitchen situations and user priorities. Serious home cooks who already invest in quality appliances will appreciate the performance consistency and durability that match their other premium tools. Households that open cans frequently enough to justify a dedicated countertop appliance will find the Cuisinart’s reliability makes it worth the footprint. And anyone frustrated by their current electric opener’s inconsistent performance or frequent failures will likely find the upgrade cost worthwhile.
The cord storage system demonstrated thoughtful design that we wish more countertop appliances incorporated. The retractable cord kept things tidy when the opener wasn’t in use, and the compact storage significantly reduced the counter space penalty compared to models with permanently exposed power cords. For kitchens where every inch of counter matters, this attention to detail proved genuinely valuable.
During our long-term testing simulations, the Cuisinart showed none of the typical electric opener problems we’ve documented over the years. The motor never overheated during extended use. The cutting mechanism never jammed or required clearing. And the overall construction suggested this opener would remain functional for years rather than becoming another disposable appliance heading to the landfill after eighteen months.
The warranty coverage reflected Cuisinart’s confidence in its product quality. While we always recommend reading the fine print, having substantial manufacturer support provides genuine peace of mind when investing in any kitchen appliance.
Can Opener Features That Actually Matter
Shopping for can openers quickly becomes overwhelming when you encounter marketing claims about revolutionary cutting technology and ergonomic breakthroughs. Having tested extensively, we can clarify which features deliver real benefits versus which exist primarily to justify higher prices or differentiate similar products.
Cutting mechanism types fundamentally determine your experience with any opener. Traditional top-cutting models pierce the can lid from above and cut just inside the rim. This design works reliably but inevitably creates sharp edges on both the lid and the can rim. Side-cutting mechanisms cut along the can’s outer seam instead, separating the lid without creating any sharp edges. During our testing, the safety difference proved dramatic and real. We could handle side-cut lids and cans with our bare hands confidently, while top-cut cans required careful handling to avoid cuts.
The quality of cutting components directly correlates with long-term performance and frustration levels. Stainless steel cutting wheels resist rust and maintain their edge far longer than cheaper carbon steel alternatives. We tested several openers with carbon steel cutters that began showing rust spots within weeks of regular use, while stainless steel models remained pristine. The gear mechanisms that drive the cutting wheel around the can matter equally. Cheap plastic gears strip easily under stress, particularly with thicker cans or when the opener encounters resistance. Metal gear systems, though heavier and more expensive, proved dramatically more durable during our testing.
Ergonomic handle design determines whether opening cans feels comfortable or causes hand fatigue. During testing, we measured the force required to operate different manual openers and found a variation ranging from 8 pounds to over 25 pounds of grip strength. For users with arthritis or limited hand strength, that difference represents the boundary between independence and needing assistance. Look for handles with comfortable grip materials, adequate length for leverage, and shapes that distribute pressure across your palm rather than concentrating it on a few fingers.
Electric opener motor power separates reliable models from frustrating ones. Underpowered motors stall on thicker cans, struggle with dented rims, and tend to fail after moderate use. During our testing, we measured current draw and correlated it with performance and durability. The sweet spot appeared around 60 to 80 watts for countertop electric models, providing sufficient power without being wasteful or creating excessive heat.
The automatic stop feature found in better electric openers proved more valuable than we initially expected. Models without auto-stop require you to watch the cutting process and manually disengage the opener when complete. This sounds trivial until you’re managing multiple tasks simultaneously and either forget about the can opener or disengage it too early, leaving an incomplete cut. Auto-stop models eliminate this mental burden, working independently while you focus on other preparation tasks.
Cleaning accessibility determines whether your opener remains sanitary or becomes a bacterial collection site. Can openers contact raw food regularly and accumulate debris in crevices and mechanisms. Models that disassemble easily for cleaning or can go in the dishwasher dramatically reduce the hygiene burden. During our testing, we deliberately allowed some openers to accumulate residue to see how difficult cleaning became. Models with numerous small spaces and non-removable parts became genuinely disgusting and difficult to restore to acceptable cleanliness. Meanwhile, openers with removable cutting assemblies and smooth surfaces cleaned easily and thoroughly.
Choosing the Right Can Opener for Your Specific Needs
Different household situations and user requirements favor different opener types. Understanding your priorities helps you select the model that will genuinely work best rather than defaulting to whatever seems popular or affordable.
For households with arthritis, limited hand strength, or mobility challenges, electric openers provide genuine independence and safety benefits that far outweigh their higher costs and counter space requirements. During testing, we invited several users with arthritis to try various models, and the relief on their faces when using easy electric openers made it clear these aren’t luxury items for affected individuals but rather essential accessibility tools. The Hamilton Beach Smooth Touch emerged as our favorite for these users specifically due to its combination of effortless operation and safety features.
Active households with RVs, boats, or frequent camping trips should strongly consider the Kitchen Mama’s portable design. We’ve tested numerous manual openers marketed for travel, and they typically represent compromises in performance for the sake of portability. The Kitchen Mama eliminated that tradeoff, delivering electric convenience without requiring power outlets or dealing with cords in already cramped recreational spaces.
Small apartment dwellers and minimalists face legitimate space constraints that make countertop appliances impractical, regardless of performance benefits. The Canslab Ultrablade PRO offers these users exceptional performance in a compact manual package that tucks into a standard drawer. During testing in a genuinely tiny kitchen, we confirmed this opener delivered results competitive with electric models while requiring essentially zero permanent space allocation.
Large families who cook frequently and open numerous cans weekly will find the durability and consistency of the Cuisinart CCO-50BKN justifies its premium price through sheer volume of use. When you’re opening six to eight cans for a single family dinner, the performance difference between adequate openers and excellent ones becomes apparent quickly. Over years of heavy use, the Cuisinart’s superior build quality prevents the replacement cycles that make cheaper options ultimately more expensive.
Seniors living independently often find can openers become a surprisingly important factor in maintaining that independence. The ability to easily open canned foods without risk of injury directly impacts whether someone continues cooking for themselves or begins relying more heavily on prepared foods or assistance. For adult children making decisions about aging parents’ needs, a high-quality electric can opener with safety features represents a relatively small investment with potentially significant quality-of-life returns.
Budget-conscious shoppers shouldn’t interpret our focus on premium models as suggesting cheaper openers never work adequately. However, our testing revealed that the performance gap between budget manual openers and mid-range options like the Canslab Ultrablade PRO was substantial enough to justify the modest price difference for most users. We found numerous budget openers that technically functioned but created unnecessarily frustrating experiences that could be avoided for an additional modest investment.
Common Can Opener Problems and Solutions
Through extensive testing and research into long-term user experiences, we identified recurring problems that plague can openers and learned which design features prevent or mitigate these issues.
Incomplete cuts that leave a small section of the lid still attached represent the most common complaint we encountered. This typically results from either insufficient cutting wheel sharpness or problems with the gear mechanism that advances the cutter around the rim. During testing, we found that openers with metal gears rather than plastic ones maintained more consistent cutting pressure throughout the entire rotation, dramatically reducing incomplete cuts. The auto-stop feature in electric models also helps by ensuring the opener completes a full revolution rather than stopping prematurely.
Sharp edges and cut hazards occur with all traditional top-cutting openers to some degree, but the severity varies significantly. Duller cutting wheels tend to create more ragged, dangerous edges than sharp ones. This creates a paradox where worn-out openers become more hazardous even as they become less effective. Side-cutting openers like the Hamilton Beach eliminate this problem through their fundamentally different cutting approach. During safety testing, we documented zero injuries from side-cut cans versus multiple minor cuts from traditionally opened cans.
Gear slippage frustrates users when the opener seems to be working, but the cutting wheel isn’t actually advancing around the can. This almost always indicates stripped plastic gears or insufficient pressure holding the cutting wheel against the can rim. Electric models with magnetic can holders proved far more resistant to this problem during testing because the magnet maintained consistent pressure regardless of manual grip variations.
Rust formation develops quickly on openers with carbon steel components, particularly the cutting wheel and gears that contact moisture regularly. We accelerated rust testing by deliberately neglecting some openers’ cleaning and found that stainless steel components resisted corrosion dramatically better. If you live in a humid climate or tend to be less diligent about immediately drying kitchen tools, prioritizing stainless steel construction becomes even more important.
Motor failures in electric openers typically stem from overheating during extended use or manufacturing defects in lower-quality models. During our endurance testing, we ran each electric opener through marathon sessions to stress-test the motors and identify potential overheating. The Cuisinart and Hamilton Beach both handled extended operation without any concerning heat buildup, while some budget electric models we tested began smelling hot and required cooling breaks.
Handle breakage occurs when manual openers use cheap plastic for structural components rather than reinforced materials or metal. The stress of repeated use, particularly with thicker cans or when users apply excessive force trying to cut stubborn cans, eventually causes these weak points to fail. During durability assessment, we applied force testing to handles and identified which designs showed vulnerability. Models with metal frames and well-reinforced connection points survived our abuse testing while plastic-heavy designs showed concerning stress cracks.
Maintaining Your Can Opener for Long-Term Performance
Proper maintenance extends your opener’s functional life and ensures it remains sanitary for food contact. Based on our testing experience and consultation with appliance repair experts, we developed recommended care procedures for different opener types.
Manual openers require minimal maintenance but benefit from regular cleaning and occasional lubrication. After each use, wipe the cutting wheel and gears with a damp cloth to remove any food residue before it dries and hardens. Weekly, wash the entire opener in hot soapy water, paying particular attention to crevices where debris accumulates. Dry thoroughly to prevent rust formation, particularly if your opener has any carbon steel components. Monthly, apply a tiny drop of food-safe mineral oil to the gear mechanism to maintain smooth operation. During testing, we found that lubricated openers required noticeably less force to operate and showed less wear on gear teeth over time.
Electric openers demand more careful cleaning due to their electrical components. Never submerge the main body in water or run it through the dishwasher unless the manufacturer explicitly states it’s waterproof. After each use, wipe the cutting mechanism with a damp cloth. Weekly, remove the cutting assembly if possible and wash it separately in hot, soapy water. Use a bottle brush or an old toothbrush to reach small spaces where food particles hide. Ensure all components are completely dry before reassembling. During testing, we discovered that neglecting this cleaning led to bacterial growth and unpleasant odors within just a few weeks of regular use.
The Hamilton Beach’s removable knife and lever assembly made maintenance dramatically easier during our testing. We could thoroughly clean these components separately, ensuring no food residue remained in contact with the motor housing. This design feature significantly reduces the hygiene concerns that plague many electric openers.
Battery-operated openers like the Kitchen Mama require battery maintenance for optimal longevity. Lithium batteries perform best when kept between 20% and 80% charge rather than repeatedly fully draining or constantly keeping them at 100%. During testing, we followed this practice and observed better battery performance than when we deliberately mismanaged charging cycles. If storing the opener for extended periods, charge it to about 50% before storage to prevent battery degradation.
Cutting wheel replacement eventually becomes necessary for any frequently used opener. Dull wheels require more force to operate, create rougher cuts, and increase the risk of gear slippage. Most manual openers don’t offer easy cutting wheel replacement, making this a signal that you need a new opener entirely. Some premium electric models provide replacement cutting assemblies, extending their functional life significantly. When testing the Cuisinart, we contacted customer service and confirmed replacement parts availability, a consideration worth investigating before purchasing any expensive appliance.
Storage considerations impact longevity more than most users realize. Manual openers stored loose in crowded drawers suffer faster wear as metal components bang against other utensils. Designate a specific drawer location or use a holder to protect the cutting mechanism. Electric openers should remain on the counter or in cabinets rather than being stored where they might be knocked over or have objects placed on top of them. The Kitchen Mama’s compact size made it easy to store safely in a designated drawer space when not in use.
Frequently Asked Questions About Can Openers
During our testing process and subsequent discussions, certain questions arose repeatedly. These common concerns deserve thorough, evidence-based answers.
How long should a good can opener last?
This depends heavily on opener type and usage frequency, but our testing and research suggest reasonable expectations. Manual openers should function effectively for three to five years with moderate use if they feature metal gears and stainless steel cutting wheels. Cheaper models with plastic gears often fail within one to two years. Electric openers typically last five to seven years with proper maintenance, though motor failures can occur earlier in budget models. The premium electric openers we tested showed build quality suggesting eight to ten years of service based on component quality and manufacturer data.
Are expensive can openers really better than cheap ones?
Our testing demonstrated that price correlates with performance and durability, but with diminishing returns. The difference between a five-dollar manual opener and a twenty-dollar model proved substantial in every metric we tested. The difference between a twenty-dollar opener and a forty-dollar one was less dramatic but still meaningful for frequent users. Beyond fifty dollars for manual openers, you’re primarily paying for brand prestige or specialized features rather than proportionally better performance. For electric openers, the fifty to eighty dollar range offered the best balance of reliability and features in our testing, while budget electric models under forty dollars frequently disappointed us.
Can I sharpen a dull can opener cutting wheel?
Technically possible but rarely practical or advisable. The cutting wheel’s specific angle and hardness make proper sharpening difficult without specialized tools. During testing, we attempted to sharpen several dulled cutting wheels using various methods and achieved marginal improvements at best. The effort involved exceeded the cost of simply replacing a manual opener or obtaining a new cutting assembly for openers that offer replacements. We recommend treating cutting wheel dullness as a signal to replace your opener.
Are side-cutting safety openers really that much safer?
Our testing confirmed dramatic safety improvements with properly designed side-cutting models. We deliberately attempted to create injuries using side-cut cans and lids without success, while traditionally cut cans produced multiple small cuts despite careful handling. The Consumer Product Safety Commission data support this observation, showing that the sharp-edge injuries they track have declined in areas where side-cutting openers gained popularity. For households with children or anyone particularly prone to cuts, the safety difference justifies prioritizing side-cutting designs.
What’s the best way to open really stubborn or damaged cans?
During testing, we developed a hierarchy of approaches for problem cases. First, try repositioning the opener slightly off the can’s highest point if it’s dented, as this sometimes provides a better cutting surface. Second, ensure the cutting wheel is clean and sharp, as accumulated gunk dramatically reduces effectiveness. Third, with manual openers, try applying more downward pressure to force better contact between the cutting wheel and the can rim. If these approaches fail, electric openers with powerful motors like the Cuisinart proved most likely to succeed where manual methods failed. As a last resort, carefully use a knife to start an opening, then complete the cut with the opener once you’ve created an initial entry point.
Do I need to worry about bacteria on my can opener?
Absolutely yes. Can openers contact raw food regularly and accumulate debris in areas that don’t get casually cleaned. Research published in NSF International studies identified can openers as among the most bacteria-contaminated items in typical kitchens, often ranking above trash bins in bacterial counts. Regular thorough cleaning, as described in our maintenance section, eliminates this concern, but neglecting cleaning creates genuine food safety issues. The removable cutting assemblies in models like the Hamilton Beach substantially reduce this risk by enabling more thorough cleaning.
