What every best Can Openers has:
- Stainless-steel blades
- Comfortable handles.
- Reasonable size.
After three years of can opener research (opening 121 cans with 23 can openers), testers recommend an inexpensive EZ-DUZ-IT manual can opener as the best for most people. They also recommend the best electric can opener. They no longer recommend smooth-edge "safety" manual can openers, because they wear out too quickly. Testers open everything from tiny tomato paste cans to big 28-ounce cans of tomatoes. They include long-term testing notes, and they also ask several experts about their favorite openers.
The editors of Cook's Illustrated test seven jar openers on everything from a tiny vanilla bottle to a quart of pasta sauce. The full details and results are available to subscribers.
The editors of Cook's Illustrated also test seven manual can openers -- both side- and top-cutting models -- by opening hundreds of various-sized cans. They judge how easily the openers attach, operate, detach and dispose of the lid, as well as their safety. The winner has been discontinued, but the two runners-up are still available.
In this older test, The Wall Street Journal's Test Kitchen tests almost a dozen electric can openers and names one clear favorite. Testers also try out an unspecified number of manual can openers, picking four favorites ranging from $2 to $50. They briefly explain the pros and cons of each pick.
An unidentified group of testers evaluate six manual can openers for features like ease of puncture and comfort of grip. Each model receives a brief review. Testers like four of the can openers, but not the other two.
Shopping bloggers Kristina Matisic and Anna Wallner ask a Meals On Wheels facility to test four manual can openers. Two traditional top-cutting can openers -- a budget pick and a midpriced one -- are the favorites. Matisic and Wallner also share tips for choosing the best can opener. Although this is an older test, all four of the can openers tested are still current, easy-to-find models.
After testing 11 smooth-edge can openers, Maryellen Driscoll finds one clear favorite and three runners-up. She writes a few sentences describing the pros and cons of these four; she names the losers, but she doesn't describe them. Driscoll finds she prefers smooth-edge can openers with their knobs on the side (like a regular can opener), and built-in pincers to remove the lid aren't necessary. Although this is an older test, all of the top picks are still current.
Hundreds of can and jar openers are reviewed by owners on Amazon. Standouts typically receive a 4.5-star rating after at least 1,000 user reviews.
This Chowhound contributor compares a 1990s original Swing-A-Way can opener with the new EZ-DUZ-IT can opener, made by the original Swing-A-Way company (the new Swing-A-Ways are made in China, and not by the same design as the old ones). The EZ-DUZ-IT works exactly like the old Swing-A-Way, even flawlessly opening a can in midair (i.e., without supporting the can on a table).
A panel of testers for Consumer Reports tests an undisclosed number of manual can openers. There's no single standout model, but pros and cons are given -- without their proprietary ratings matrix -- for five models that seem to have generally operated well. This article is free to read, even by those that don't have a subscription. It's an old article, though, and two of the five can openers discussed have been discontinued.
Walmart sells several popular brands of can openers, although not as many as Amazon. One electric can opener earns a 4.6-star rating with more than 900 customer reviews posted.
