I've been using 800 "grit" diamond sharpening blocks I use for my wood plane irons and wood chisels on hobby knife blades for years. If I want one REALLY sharp, I use my Japanese water stones then my straight razor strop. (Yes, I've used an Otto Fromme straight razor since I was 18 everyday. And I can and have shaved in the dark, and I never nick myself. I also use a cup and soap block too.) X-atco blades ain't that sharp from the factory, IMHO. I've been buying Harbor Freight Chinese blades for $6.00 for 100, and spend time in front of the TV putting a real edge on them. PS: Any tool-guy can tell you stainless steel makes a
terrible cutting instrument. My Great-grand-mother's Case cutting knife is spring steel and will rust in minutes, but it will hold an edge like no knife sold in 80 years will.
