This oak knows exactly what he is saying. . . You just won't beat a Adamas with that beefed up axis. Anything else I'm sure you could eventually fail. I have failed zt, spyderco, others with frame and liner. But never a never an axis. I have no experience with cold steel locks... but sounds good. We need someone to put a hard use test with Adamas and spartan together... would love to see who wins that battle! I'm confident that Adamas will kill spartan, but would love to be proved wrong.
