Thanks fellas.
All hand stitched by me. I first scribe a really light line using a small caliper tool, then run a "craft over stitch wheel tool" from Tandy. The tricky parts, and the part that I am least satisfied with, is drilling the stitch holes. I use a small bit, and even when I have used a drill press, the back side of the sheath's stitch line wanders.
At any rate, they last. I glue up the welt and the sides using "titebond II or III glue, really seems to work well, once it's dried, I have to rip the leather apart to undo it. So the stitching is really more cosmetic I suppose.
Also, I have begun using a snap on the belt loop. Quite handy for taking it on and off a belt or a pack strap!
