ZT 0560/61 and 0550 Lock Face HT Q?

[Szilard]

Hey BF -

I was recently watching some of CrimsonTideShooters videos about early and late lockup. He mentioned that Sebenzas and Hinderers don't have much of a problem even if they have late lockup because they heat treat the lock face through carburization. I was wondering if ZT/Kershaw also heat treats their lock face with similar results?

I'm not too concerned with it - I don't actually even flick my 0560 as much as I'd enjoy to, I'm just very interested with manufacturing processes and the reasons behind. If anyone has a definitive answer I'd appreciate it, I couldn't find it via search.

I don't think they do, atleast it doesn't look like it.

jimmer_5 confirmed in another thread they are carbidized (meaning tungsten carbide is impregnated into the lock bar face, and it is harder than titanium, in the 70s hrc).

edit: By the way, CRKs are heated to put on a hard oxide layer (I don't believe that can be called carburization, which involves adding carbon to a low carbon steel, since titanium doesn't contain carbon, and the heat applied to CRKs is just to add that oxide layer). Hinderers also aren't carburized; they're carbidized.

edit2:

THe 0560's have always been carbidized.

Thank you Kreole for that excellent answer. Sorry for the mix up of terms, I have more learning to do.

In case anyone else wanted to see for reference.

Does that mean the 0550s are not carbidized?
