Back to work! Important question, how sharp do you want the blade? 440 is the designation for a class of high, medium and lower carbon chromium stainless, hardenable, steels. The three different classes of 440 are, "440A", "440B" and "440C". The letters stand for the carbon content therefore the potential for hardenability during heat treat. Of the three, 440C has the highest carbon and makes the best blade. Carbon content of steel and heat treat have a great deal to do with how sharp we can get a blade. How to test the edge next.
