While in Gatlinburg last week I met the Mohr Brothers http://rickmohrcustomknives.com/
and purchased several of their knives. They use "found steel" (saw blades, files, etc.) to make truly beautiful blades. I met them through Country Cobbler in Gatlinburg. Doug offered to make a holster for my Single Six then made several sheaths for most of the knives. Here is one I especially like:
If you are ever down Gatlinburg way, stop buy - Doug is a hoot to talk with and will drop everything and build you a sheath or holster in a couple hours.
