It's very easy to use-tap twice to open any can, cut 360 degrees along the lid, then press the button again to stop. You'll get a smooth cut to keep your hands safe. Then stash this compact tool in your drawer until you need it again. One drawback is that this requires AA batteries to operate and must be purchased separately.
