I use the Spyderco Sharpmaker for Everything. I have been sharpening knives for 25+ years and always used the vintage crock stick style sharpeners. The sharpmaker is just an improvement of a tried and true design. It offers a 30 degree and a 40 degree sharpening angles. You can also sharpen scissors, fish hooks, etc. They run about $50, but well worth it. I also picked up the ultra fine stones and these put a mirror polish on the edge and also add that extra hair popping edge. The also make diamond coated rods for heavy reprofiling, but I never got them. The rough brown stones will work for that, just takes some extra time.
