I don't know about that PARTICULAR Crosslock,
but I bought my stepdad, who's a tow-truck driver/business owner
a Crosslock SEVERAL years ago. It was one that was plain-edged
on one blade and fully-serrated for the other blade. ATS-34 steel.
This guy has abused the living HECK out of this thing over the years
until the lock goes all the way over to the other side and he still
beats the heck out of it.
I bought him a Spyderco full-sized Dyad (same blade configuration)
to replace it because I figured the Buck was worn out in my view,
but he just stuck the Spyderco in his sock drawer and has STILL
been using his Crosslock for the last year-and-a-half since then.
Based on the experience of a guy who scrapes battery terminals
with his pocket knife (and god-knows what else he does with it)
for a living, and has done so with a Crosslock for about 4 years,
I'd say the Crosslock is a WAY tougher knife than you'd expect
from any production knife.
I'd buy him another one of the same thing if it were still available.
