This little can opener is amazing! It's great in both quality and functionality. It's extremely small and light and is a great addition to my backpacking gear!
Ok - that was fun. I've known of these things but never used one. Did it require a lot of cranks to open that can of beans? Yes. Was my finger and thumb a little sore? Yes.
