Manual or electric?
Can openers come in
many styles, from the nearly effortless electric models to the tried-and-true
hand-crank models that work just as well today as they did in decades past. The best can and jar openers can handle a wide variety
of can or lid shapes and sizes without jamming, cutting your fingers or
requiring a lot of hand strength.
Types of Can Openers
From models that are little changed from the ones your grandparents used, to modern devices that offer improved safety and convenience, manual can openers remain the most popular choice. Most are easy to use and reliable, but some level of manual strength and dexterity are required.
Jar openers are tools that either clamp or slide onto the jar lid, providing extra leverage to help you get the jar open. Most jar openers require some (minimal) hand and wrist strength, but owners find they're still a big help for those with arthritis or limited grip strength.
Once exceedingly popular, under-cabinet can openers are not as common in kitchens now. However, they still remain a great choice if you don't want to lose any drawer or counter space to your can opener.
Electric can openers reduce the process of opening a can to the flip of a lever or push of a button. Though they can take up a bit of counter space (space-saving under-cabinet models are also available), electric can openers are especially helpful if you have limited hand strength. Some will even stop automatically once they've completed the cut.
Top-cut vs. side-cut can openers
Can openers can be top cut or side cut, and each type has
its pros and cons. Many of us have learned to accept the risk of sharp, jagged
edges when opening metal cans with a top cut opener, but side-cut (also called
smooth-edge) can openers change that by cutting along the side of the lid,
splitting the seam where it joins the can and leaving smooth edges on both
Safer than traditional top-cutting models, smooth-edge can
openers are popular with parents of small children. They're also a great choice
if you're buying for an elderly member of the family or are just tired of
fishing top-cut can lids out of your food (a side-cut lid will not fit into the
body of the can). Plus, a side-cut can opener's cutting teeth never actually
contact the food, so they're more sanitary, rarely need to be washed (according
to users), and are thus much less likely to rust than their top-cut
But smooth-edge can openers still aren't perfect. Because
they don't leave an obvious separation, it can be hard to tell when you've cut
all the way around, and if you cut around more than once, you risk creating
sharp metal slivers that can get into your food or cut your fingers.
Durability is a continuing issue with smooth-edge can
openers as well, and getting the lid off is sometimes a challenge. Some side-cut
openers come with tiny pliers to help you grasp the lid and pull it off. Owners
occasionally complain about the cutting blade of their smooth-edge opener
dulling over time, requiring them to circle the can more than once, which, as
noted above, creates metal slivers.
Top-cut models seem to last longer and open cans more
dependably than their side-cutting counterparts, perhaps due to more robust
cutting blades. Top-cut models are often equipped with magnets to keep the cut
lid from falling down into your food. Both of the highest-rated handheld can
openers are top-cut models, although we did find one (more expensive) side-cut
model that's worth considering. If you are considering an electric can opener,
our top pick among those is a side-cut model.
