Mods, feel free to move this to the cantina.
Oldschool, here are the requested photos:
The back. You see where I tied the stitching, including where I broke the thread while lacing. The back is not as nice as the front, but that's where the work is!
The welt. I really didn't know how to do this part, other than stack leather. I didn't have any thick stuff available. I just kept stacking what I had. This photo also shows how the pig skin lining doesn't want to stick to the edge.
Dan, since this is my first sheath, I started like this:
Traced the blade on poster board, used the $.99 compass (which didn't work very well) to give space for the welt and stitching, cut the paper "models", traced the shape onto leather with a pencil, cut the two sheath halves, cut the welt from the "model", traced the welt onto leather repeatedly and cut them out, glued the welt in place, glued the two halves together, used the compass to make a line from the sheath edge about where I figured the middle of the welt was, used this new fangled four punch thingy to set the spacing (four marks at a time), drilled the holes, then stitched it together. then I sewed the D-ring straps in place. That's it in a nutshell!

Before I connected the two pieces, I sewed the belt loop and retaining strap, but it's really that simple. I probably missed a step and I'm sure others can fill in the gaps. Just go slow and check everything often. I thought it would be very loose, but it is actually very snug. Much better than I expected. My next one might not even hold the khuk in! I'm learning this sheath business slowly, but it's fun to make something. Also, look at what others have done. I based this loosely off of a CS LTC sheath I have and added some ideas from Mr. Paul Long, who is actually just up the road from me and makes stunning sheaths. Thanks and take care everyone.
