I haven't decided yet if I'm going to pick up the diamond rods for the Sharpmaker or drop the hammer on a belt grinder, maybe both. I like the idea of using the sharpmaker for flat grinds on my folders and the belt grinder for convex edges on my fixed. I'm getting better after playing with the Sharpmaker, I got a few kitchen knives shaving sharp now. Just need a Bird Dog or Mudpup to round out the kitchen set.
