I got this kit at Bass Pro a year ago. I sharpened my KA-BAR with it before season. A bud and I cut the heads off of 3 250+ lb boars with it in one day. Went home and had the knife back like a razor in about 10 minutes. It comes with easy directions and set degrees at which you can sharpen the knife. I think for the $$ it would be the best kit to buy. Works great in my opinion.
