Congrats on the War Dog! <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />

In general I prefer leather, it just looks and feels better to me, however I do find myself using kydex for certain aplications as well. A well made kydex sheath should have very little effect on the handle though, but any time you rub two things together a few thousand times there will eventually be some wear no matter what, it's inevitable. That applies evenly to leather as well as kydex though. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

Just get yourself some pants for that blade and get out and enjoy it! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
