Input:
It makes any blade razor sharp in seconds. Read the instructions on how to use it though. I had another one of these before which I lost and I recently found out that I've been using it wrong the whole time. Ideally you're supposed to put it on a flat edge and slide the knife over it, not hold it in your hand while you sharpen like I've been doing. But either way, you will still get VERY sharp blades in a matter of seconds. Worth every penny. Every kitchen, camping kit, or fishing tackle box should have one.
