The best things I've found are those broadhead sharpening wrenches. Those little hand held things with the two small carbide teeth. They farm a V to set an edge. I sharpened some knives with one of those and was very impressed. I got cut when doing my Ka-Bar. Unfortunately I lost mine <img src=icon_smile_sad.gif border=0 align=middle> but it's not too bad 'cause they cost like $7

God bless,
