I follow Ed Caffrey's process for hardening my 5160 blades. So far I have had good reports on my 5160 knives but to tell the truth I have not tested this particular blade yet. It still is unsharpened. I leave them that way until I have the sheath completed(saves on Band-Aids). I like leaving some of the forge marks in a blade, (unless the person I am making it for does not want them.) partly for aesthetics and partly because it takes a long time to draw file out forge marks. I really need to get a grinder someday, Whew! Thanks for your gracious comments Gentlemen.
