Kydex has no character... <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />

One of the coolest ideas that I like for a military use type sheath is a leather lined kydex set up. You get the durability of kydex and the quite draw and general sound deadening qualities of leather. Of course I have also seen gun holsters made the opposite of that, with kydex inserts in leather holsters.
