I've got a little of it, and have forged a blade out of it. Haven't gotten far along to the heat treatment stage, but I can tell you it forges very easily. Much more easily than L6 or W2. 6150 has a little less carbon than 5160, but contains vanadium, so edge holding should be decent to good. Probably not going to hold an edge like O1, but should be a good bit tougher.
