Jeep - I have two set ups, one is for sale as I have found the one that I will not part with.
The first is a Lansky (http://www.firearmstalk.com/forums/f41/jds-shot-show-clearance-36344/
) and it's a great system for most blade applications.
The second, the one I used for the knife I sent Benning, is from Benji Dale in Oregon and is called the Edge Pro Apex Sharpening System. While this system won't do concave blades well, like a Karambit, it will sharpen the hell out of just about any other blade on the planet.
Ask Benning to show you some picks of the Mil-Tac I sharpened for him.
