Johpe, I am sure that 13 deg. makes for a seriously sharp edge and I’m glad to hear it works well for you. I may attempt to put it on one of my older knives to test out. Thanks for giving me one more thing to try. This hobby never gets dull.
Now I’m thinking about getting my next kitchen knife in hap40 steel, people on other forums claim it should be unbelievably great for sharpness and edge retention. Anyone here that has any experience with it?
