A few of my SYKCO's have not-quite-perfect tubes and the Res-C by them is a bit rough.

Never bothered me either. Doesn't affect the performance of the knife, and I know they inspected them for stuff that would.

I've beat a couple of them half to death and they've always begged for more.

But your opinion is what matters here, bro. It's your knife. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
