Be safe! The Safety I-Can™ Opener prevents sharp edges while opening cans. Revolutionary ratchet design reduces hand and wrist strain and comfortable grip makes it effortless to use, no matter how many cans need opening. Designed for right or left handed users - just clamp onto can securely, rotate the ratchet back and forth, open handles to release the can. Use the teeth on the side of the can opener to grab onto the edge of the rim and lift upward, removing the lid without touching.
