Awhile back, one of the best of the blade smiths said that well treated 0-1 would out cut any Damascus, and no one argued with him. Edge holding is exceptional. 0-1 is precision ground unless you're lucky enough to stumble across some mill bar. Goof up the heat treat and 0-1 will let you try again as often as you like, as long as you don't overheat the metal. Tough on grinding belts. It's significantly tougher, with finer crystalline structure and hard graphitic particles that resist wear.
Stock is both hot rolled and precision ground.
Hot rolled prices are reasonable. Very tough to grind. Edges are incredible, lasting even longer than the best Damascus and even 0-1. Has an odd, rather orange spark. Toughness is outstanding, with these alloys being used for grader blade edges, truck springs and files.
