Best Can Opener of 2021
It's easy to attach any size can to the Hamilton Beach Smooth Touch, and this was our overall favorite electric model. The guiding bar above the blade places the can in the perfect spot every time. The oversized locking lever is easy to use, and the smooth touch design breaks the can's seal along the lid's edge instead of breaking through it. The result is an opened can and lid with smooth edges, hence the name. Very little of the contents of the can remains on the opener's blades, creating minimal clean-up, a bonus of this design.
The Smooth Touch isn't without its flaws, though. The guiding bar and all of the gears for can attachment are made of metal, but the lever that controls the locking mechanism is plastic. The introduction of plastic levers and electrical elements draws durability into question. The countertop design doesn't have any additional features like a bottle opener, and it requires a lot more space than the handheld models — considerations for those who infrequently open cans or lack excess counter space. That said, this opener's chrome and black look is timeless and sleek, so it's not an eyesore on your counter. Overall, the Hamilton Beach Smooth Touch is the best option if you open lots of cans and desire the easiest solution available.
For the best overall manual performance, the classic style of the EZ-DUZ-IT just can't be beat. This opener looks just like the one many of us grew up using, and probably the one our parents grew up with as well. The EZ-DUZ-IT Deluxe sticks to a classic all-metal construction with rubber grips that slide over the handles. The metal construction earns the model top marks in durability. The metal handles are covered in grippy, comfortable rubber. When attempting to puncture large cans, the grips, combined with the rigidity of the metal, give a great mechanical advantage. This opener performs equally on everything from small 6 oz cans of tomato paste to large 28 oz cans of crushed tomatoes. Besides being just about as affordable as a can opener can get, it is also exceptionally durable, a combo we salute.
While the EZ-DUZ-IT is a great traditional option, there are a few areas it falls a little flat. The tendency to disconnect from the rim of the can when there's too much downward pressure on the handles is the most notable. This results in the lid being very difficult to remove because it is still attached in two places. Although initially frustrating, a little bit of practice mitigated this issue. Additionally, this no-fuss design does lend itself to creating sharp edges on the can's lid, as is common with this opener style. This might not be the best option if you have impaired dexterity or small children helping in the kitchen. However, with a bit of caution, the lid is still possible to remove. If you are looking for a good old-fashioned can opener that has the potential to outlast the competition, the EZ-DUZ-IT Deluxe is the opener for you.
If you're seeking the luxury of a countertop electric can opener with a manual can opener's price tag, check out the Cuisinart Deluxe Electric. You can have this white, sleek countertop model for just a little more than most manual can openers. The magnet feature holds on to the cut lid for easy removal, and the large lever makes it easy to puncture the tops of cans of all sizes. The auto-stop feature stops the opening and holds the can as soon as the lid is completely removed, making for easy, hands-off use. Additionally, the magnet and blade are easily removed for cleaning away from the electric parts.
Out of the five commonly available can sizes tested on each opener, two remained stuck in the Cuisinart's locking lever's clamp during testing. They were removed with a little additional pressure, but it was easy to spill the can's contents while doing so. Another drawback of this style is that it creates a jagged and sharp lid. The magnet makes it easy to remove the lid, but this isn't the best option if you have small children or would prefer a smooth edge. Additionally, the locking lever, the casing around the magnet, and the socket that attaches the blade/magnet to the body are all made of plastic. These high-use parts might lose some of their sleek chrome appearance as the paint chips away or wear down over time. Overall, we feel the Cuisinart works better than expected for its entry-level price if you are looking to try an electric model.
It says "Yes You Can" right on the pink box, and, well, yes, it can. The Kitchen Mama Electric is a surprising standout. Out of the box, its fun pop offers something different from the otherwise modest-looking competition. After taking a few moments to determine exactly how to place the compact electric opener on the can, attaching it becomes effortless. The single button that operates the Kitchen Mama is easy to press and securely locks to the lid's edge for hands-free operation. Once the opener makes a complete rotation, pressing the button stops the opener and detaches it from the lid. The result is a smooth lid and can, with no food product left on the opener. Even the smallest cans did not cause any issues for the Kitchen Mama.
There are just a few downsides to this opener. It operates on four AA batteries, which leads to an additional cost of upkeep. Also, as a handheld electric model, it is likely to be knocked off of the countertop from time to time. When we tested this model for its drop-resistance, the battery casing popped off, and the batteries scattered. Though we didn't experience any cracking during our drop test, we would recommend exhibiting care to not drop this model, as the plastic shell feels somewhat thin. Overall, we were very impressed by the Kitchen Mama, even if you have to replace it eventually. It takes minimal effort to operate and produces a smooth lid and can. All in all, this is an excellent and hip solution for those who struggle to operate a traditional opener or who don't want to add an appliance to their countertops.
The Joseph Joseph Can-Do Compact is at least a third of the size of any of the openers we tested, clearly earning its place in some kitchens. It is only 2" in diameter and about the same in height. This is a good option if you need a little can opener for camping trips or have limited space. The Joseph Joseph attaches securely to the can's lid, and it takes moderate effort to turn the timer-like plastic dial. Once it is through the lid, and after lifting it off using the locking feature, pressing the release button on the opener's side takes firm pressure. Left-handed folks will appreciate that this model works ergonomically for either dominant hand.
While the Joseph Joseph is interesting in its colorful style and innovative design, it leaves room for improvement in its performance. Its design removes the entire top of the can, cutting just below where the lid is sealed. This created problems in the smoothness of operation for us, because the labels on the cans almost always became caught in the gears. Additionally, it left an open can with a sharp edge that lacks stability due to removing the thicker metal on the rim. This opener became stuck on some of the larger cans tested. After testing all ten cans, the button release function was already showing signs of wear, becoming completely stuck on the can's lid. No other option saves kitchen space better, though it's unclear how long the Joseph Joseph will perform.
As the name suggests, the OXO Good Grips has the nicest grips of the manual can openers tested. The grips are soft, textured, and maintain their functionality even when wet. This was a nice contrast to some of the smooth plastic featured on the other options. Turning the opener is relatively easy due to the oversized round knob. After a few tries to figure out the best angle to hold the opener to the can, the blade slices smoothly and evenly. It performed well on the smallest cans and is the most compact of the classic can opener styles we tested. It also includes the additional feature of a bottle opener.
While the grips are nice, puncturing the cans proved more difficult with this model. The handles' plastic structure leads to a lot of flex, which increases the force you must use and reduces your mechanical advantage. This is not the best fit for you if you do not want to or cannot use a lot of force. The plastic spacer in the gears and the plastic in the handles lead our team to question its longevity. Though not a poor option, we think there are some better models out there than the OXO Good Grips; however, none with as nice of handles.
The Kuhn Rikon Auto Safety Master shares some features with classic models of can openers, such as a bottle opener and a large knob to turn the gears. The way it connects to the can, however, is unique. It is easy to get the opener to latch onto the top of the can and break the seal along the edge. This opener also includes the additional features of pincers for lid removal, a pull-tab opener, and an opener for twist-off bottle caps. No other model we tested featured quite as many additional features.
This opener can do many things, but there are a few areas in which it falls short in our eyes. The Kuhn Rikon showed difficulty opening the large diameter cans (28 oz and up), digging into their side, and creating a dent where the lid could not be removed. As far as performance, the switch for the lid removing pincers required a lot of pressure, and the release function (turning the knob counterclockwise) was inconsistent. Lastly, outside of the blade and gears, most of the opener is made out of plastic. It seems likely that the high-use parts like the pincer switch will wear out with extended use. In addition to its four bonus functions, the Kuhn Rikon provides decent can opening capabilities.
With several different bright and stylish colors, the KitchenAid Classic is a traditional manual can opener design. The large, oversized knob is easy to turn. The long handles help lend a mechanical advantage when puncturing the can, making it a little easier than some compact models. Additionally, KitchenAid Classic boasts a high-carbon stainless steel blade.
While the brightly colored plastic and oversized handles and knobs are aesthetically pleasing, they also created a few functionality issues during our tests. The opener's large size is suitable for most cans, but the smallest cans made it feel a little awkward. It also takes up a lot of space in a kitchen drawer. The plastic on the grips is light and slippery, which can make this opener challenging to use. This was the most colorful of the openers we tested and would be a great addition to a kitchen that prioritizes aesthetics.
The KitchenAid Multifunction is another good middle of the road option for a slightly more stylish opener. We really liked how the larger size of the handles provided good leverage to puncture the can's top. The oversized knob is another great feature providing additional leverage, as it helps to turn the gears more smoothly when cutting the lid. This opener also includes a bottle opener at the top of the product, making it simple and multifunctional as described.
Where this model fell a little short was in its durability and versatility. The handles and the knob are made of plastic and can be felt flexing when puncturing the top of the can. This plastic also makes the handles slippery when either wet or dirty, detracting from its ease of use. The large knob and handles make this model a little tricky to use on the smallest cans, even though they help with leverage. Overall, if you're looking for a simple, multifunction design to fill your opener needs in a pinch, the KitchenAid Multifunction will fit the bill, but we don't expect it to last a lifetime.
At first glance, the Zyliss Lock N' Lift is a great option that assists with the sometimes tenuous task of removing the cut lid from the can. It locks securely to the top of the lid as the name suggests and has a magnet feature to help remove the lid from the can. The rubber grips on the plastic handles are soft and tacky.
The Zyliss Lock n' Lift's performance was disappointing to our testers, who had high hopes for the model. The handles had a great deal of flex in their plastic, and the blade was not sharp, leading to poor puncture ability. The lock button is also plastic, difficult to use, and feels as though it is about break. Unfortunately, the magnet does not attach securely to the lid and often comes detached before the lid is removed from the can, leaving the user with a sharp lid to remove from the can. Overall, the Zyliss Lock n' Lift was promising, but the features that made it unique did not perform well for us.
Why You Should Trust Us
Jackie Kearney, our lead tester, has spent nearly a decade working in the restaurant industry, performing every job from washing dishes to cooking to serving. She's also an adventurous home cook. In the winter, she works long days ski patrolling, and in the summer, she works long days on a vegetable farm. This experience and lifestyle mean she is passionate about finding the most efficient and effective kitchen tools. After spending years running around restaurants and running around during the day, she knows nothing is better than the perfect tool for the job. As far as cans are concerned, she's not only an expert in opening them but also in consuming their contents.
To find the best can opener models across different styles, our editorial team and lead tester spent hours researching the best available can openers. We selected a wide range of models to test, from traditional manual ones to innovative openers to countertop models and more, putting them all head to head in comparative analysis. In the process, we opened 100 cans of all sizes, from tiny 2.25 oz cans of olives to 28 oz can of crushed tomatoes, and many sizes in between. We assessed how much effort, pressure, and precision each tool demanded from us, noting the easier ones from the finicky ones. We also examined how they open cans and if they left behind sharp edges. Our leader tester intentionally dropped each model from counter-height onto the kitchen floor to ensure they can handle real-life accidents, too. After living in our kitchen drawers for weeks and getting daily use, we feel confident in our assessments and experience with each model we tested.
Analysis and Test Results
A can opener is an essential tool for any home cook. Having the right one can save you a lot of time, effort, and frustration. The openers were scored on their sharpness and smoothness, ease of use, versatility, durability, and style and footprint.
Smoothness and Sharpness
When scoring this metric, we considered the cutting performance of each opener. Testing a minimum of nine cans for each opener gave us a good idea of the consistency of each opener's cutting power. It's frustrating when a can opener pops off the can while in use, or becomes stuck halfway around the can, leaving you with a can that is neither open nor closed.
Scoring by far the highest in this category are the Hamilton Beach and the Cuisinart models. They have the advantage of electricity, as does the Kitchen Mama Electric, and continued through testing to cut open cans evenly and consistently. Edging out the manual competition is the EZ-DUZ-IT Deluxe with slightly stronger cutting performance than the OXO Good Grips, Kuhn Rikon and both KitchenAid models. The Joseph Joseph 's design removes the entire lid, creating more resistance, while the Zyliss Lock n' Lift appeared to simply have a duller blade than its competitors.
Ease of Use
Ease of use describes the opener's function outside of the blade performance, and the quality of the opened can it produced. We counted exactly how many turns each manual can opener required to open five standard cans of beans (15-16 oz), evaluated the pressure necessary to open the can, assessed the quality of the lid after it was removed and how easy it was to remove it, took into account the sound produced by the electric openers, considered ergonomics, and considered how easy they would be to use for someone with impaired hand strength. This all boils down to how convenient the product is in daily life.
Again this metric favored the electric models. It was hard to ignore that the Hamilton Beach Smooth Touch, Kitchen Mama, and Cuisinart Deluxe Electric require minimal effort to operate and produce open cans that are either smooth or sharp, but easy to manage. Each of these models merely involves attaching the can, pressing a button, and stepping away, and they open up cans with no additional effort necessary. The Hamilton Beach and Kitchen Mama resulted in the smoothest can and lids after opening up garbanzo beans or cans of tuna, leaving behind no sharp edges for kid- and adult-friendly finger preservation. We're all clumsy to an extent, and removing sharp edges from the equation is pretty sweet.
As far as manual openers go, the EZ-DUZ-IT edges out the competition with ease. With its heavy-duty and no-nonsense construction, it is still comfortable and provides a good grip. Some of the openers, such as Joseph Joseph, Kuhn Rikon, and Zyliss Lock n' Lift lost points where their additional lid removing functions caused more trouble than they helped. Even with the oversized grips, the KitchenAid models proved to be just a little too bulky to be comfortable to use. Additionally, the smooth plastic featured on both of these models made them slippery when wet or dirty, and therefore harder to use.
You probably will only have one can opener in your kitchen, so it had better perform well on anything you throw at it. To evaluate versatility, we assessed how the openers performed across all the can sizes we could find at the supermarket: 5 "average bean cans", 1 small tomato paste, 1 large crushed tomatoes, 1 short wide can of chicken, 1 short tuna can, and 1 small tomato sauce can. We also considered additional features of the openers.
Almost all of the openers performed evenly across can sizes. The exceptions were the Joseph Joseph and Kuhn Rikon, which struggled on larger diameter cans. The KitchenAid Multifunction and KitchenAid Classic struggled on short cans due to their oversized nature. The Joseph Joseph, Hamilton Beach, Cuisinart, Kitchen Mama, and Zyliss Lock N' Lift do not serve any multifunction capacity. Both KitchenAid models, EZ-DUZ-IT, and OXO Good Grips all have a bottle opener function, and the Kuhn Rikon has five extra features in addition to its can opening ability. In some cases, these additional features added a bonus to compensate in areas where the opener might have otherwise fallen short.
We have all used can openers that can barely stay attached to the lid of the can, and there are few things more frustrating when you are trying to prepare a quick canned meal than struggling to use your beat-up can opener. Whether this is due to failing gears, dulling blades, or failing plastic, the frustration is the same. To evaluate durability, we examined the materials of the high-use parts. For the handheld models, we performed a drop test from a 40" countertop.
With its tried and true all-metal construction, the EZ-DUZ-IT Deluxe crushed the competition in this category. In general, the more plastic that is introduced into a model, the less durable it seemed. Notably, the OXO Good Grips has a plastic spacer in its gears that doesn't inspire long-term, frequent use, and the Zyliss Lock n' Lift is made almost entirely of plastic. Additionally, the KitchenAid Classic Multifunction had plastic handles and knobs, pulling its durability into question. Its handle popped off in the drop test, although it still worked after that. Similarly, the Kitchen Mama fell apart during the drop test. For the countertop models we tested, the Cuisinart had significantly more plastic integrated into its can-opening mechanism than the Hamilton Beach Smooth Touch, making it seem less durable.
Style and Footprint
Style can be a personal choice, but some models stood out for their innovative designs, colors, and their efficient use of space in the kitchen. We evaluated the aesthetic design and measured the footprint of each can opener.
The clear leaders in this category for both their compact footprints and innovative designs are the Kitchen Mama and Joseph Joseph. The Joseph Joseph is the best option if you value saving space over all else, while the Kitchen Mama manages convenient performance and space the best. For its fun color choices in a market where bland looks are par for the course, the KitchenAid Classic also scores points. The Hamilton Beach has a classic design that could match most kitchens but has a relatively large footprint compared to the rest of the board. The Cuisinart countertop model is very similar in size.
Through thorough research and hands-on, independent testing, we assessed a wide range of can opener models to find just the right style for your needs. Combining personal and professional experience, we developed an extensive and structured test that focused on key performance factors, highlighting the best and worst contenders in each metric. The gobs of cans opened and gulped down in our rigorous testing process familiarized us with each product's advantages and pitfalls, so you can make an informed decision quickly to get the can opener that fits your kitchen's needs.
