Only the first prod. and the first "run" of BM42's are 12C27 steel. If I'm not wrong, BM is switching to 440C stainless for the 43, 47, and I think the new 42's.
From what I've heard, 12c27 steel is one of the few steels actually produced and engineered for knife blades, (unlike 440c).
I have found mine to be excelent for "shock resistance". I have dropped mine on concrete, pavement, rocks, and assorted other hard stuff, amd there has been almost no damage.
I don't think that I have heard of anyone breaking the blade on their 42. This has been a problem with other steels.
Some other people say that it's too soft to hold a good edge, but I haven't had any problems.
I also heard that the BM42 is the only knife that BM makes that uses this steel, which is also why they are going to switch to 440c.
I'm sure that there has been posts on this in the past.
Any help from the Bretheren???
