Also, he neglected to mention that CRK hardens the lockbar face. He made a big fuss about the ti wearing out on the S35VN. "They need to slap a steel insert in there." Ahh, no they don't.![]()
Great replies to this thread, but I wanna clarify one thing that you have said a few times.
6AL4V titanium cannot be hardened by heat-treating.
Heating titanium can form a thin (a few microns), hard layer of titanium oxides, but it does not change the hardness of the titanium underneath.
Most knifemakers agree that heating the lockface does help with the stickyness of a titanium liner/frame-lock, but I haven't read that it improves the locks longevity to any useful degree.
Heat can change the properties of 6AL4V titanium in other ways, but hardness isn't one of them.
Simply sharing some interesting information I learned on the forums...
