It takes three hands to open a can with a Swing-Away can opener. One hand to hold the grip, a second hand to turn the crank, and a third hand to hold the can. This is because the cutting wheel will walk over the rim of the can allowing the can to drop away from the can opener. This might be annoying if you are opening a can of something you can pour out of the can easily, but if you are opening something like chilled cranberry sauce or refried beans, which requires removing both ends of the can and allowing the contents to slide out in a cylindrical shape, this can opener is going to dump the can into the bowl, pot, or whatever food dish you are working over. In a restaurant, that means you dispose of the contaminated pot full of food and start over. So, unless you have three hands, or desire a can opener that requires two people to use, then this particular piece of equipment is not for you.
