I bet they are pretty close. What I don't know is how similar is the KaBar heat treat process to the heat treat that was on the old 0170-6C Becker.

Take two identical steels and let two different makers heat treat them and you now have two different steels. Case in point, Busse 154CM! Nobody else gets 154CM to behave like Jerry can, and that's all about the heat treat.

I am by no means trying to imply that KaBar doesn't know how to heat treat, just pointing out a sometimes little thought about fact.
