I have to admit that I'm not sure of the practicality of a over the shoulder carry sheath for most applications. It's probably more of a convenience. If it can be rotated to the front for re-sheathing it's pretty handy I guess. History does back up Ted's observations.

Having said all that, the vast majority of sword sheaths I make are for over the shoulder, across the back carry. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
