Hands-free operation! Opens any size can, attach to can and watch it go - it walks itself around the can - it cuts - and done! Prevents cuts and injuries unlike your old knuckle buster! Ergonomic shape fits your hand! Cordless and portable this battery operated can opener can go anywhere, in the home, boat, RV, campsite, airplane, or more! Stores neatly in a drawer to save valuable counter space! Requires 2 AA batteries not included. Great for those without a lot of strength in their hands too!
