I use a combination of two kits, I use the blade clamp from Lansky and the hones "stones" from a DMT alligner kit that are diamond.
I started with a lansky 10-15 years ago and the stones wore alot allthough they offer a diamond kit I've tried both and prefer the DMT. It takes about 10 minutes to first set the new profile,grind to a new knife but after that touch-ups only take literally 1 minute, and I'm talking about scary sharp!
I've used this system on everything from utility knife blades to multi tools, fixed blade hunting, kitchen, pocket knives even arrows, it's consistent and true so you don't have to worry about scratching up the blade.
Hope this helps!
