KME is the most sophisticated and thus "best" sharpener I've so far encountered. The genius incorporated in that "simple little tool" is staggering to a technological Neandertal like me. Ah, but how then did I/we get by -- knifes, broadheads, axes, tools -- with just a file and Arky stone for more than half a century? Easy ... I was better at (almost) everything when I was younger. So at home these days it's KME. In the field it's a diamond bar and one of those crossed carbon-stick thingies I've never really figured out what properly to call. And if I were still smart enough to carry only carbon-steel knives, in a pinch, I could still touch up a blade on a hunk of sandstone. "Everything in life is relative ...except relatives." dave
