Those are nice looking knives, Trand.
I've only sent one knife back to Case for warranty work - a new yellow CV Mini Trapper on which the clip blade was rubbing the liner. It came back about half way between being centered and the liner ..... I asked for, and would have preferred centered, but at least it's not rubbing any more. Perhaps they would do better when working on a TB rather than just a "regular" knife.
Again, just one isolated instance here; I have heard lots of good regarding Cases' warranty work. Good luck & best wishes!
