I finished the HEST sheath last night. For a first time gig I was pleasantly surprised at how well it turned out, though I need to work on cutting technique when it comes to curves and such. Maybe a set of metal french curves are necessary for use as guides. I also need to work on being deliberate and more consistent with my stitching placement. Next step is to find a pocket clip somewhere so it can be worn as a low profile pocket, IWB or boot sheath. As you can see it's very low profile. I need to get some thicker stitching too, or a smaller punch... but definitely 100% functional and I think the design is sound. I'll start making round 2 and 3 for the RC3 and Paklite Skinner. This was about 5 dollars in leather, a 3 dollar stitching awl and a 5 dollar leather punch and a negligible amount of rubber cement, as far as materials. Total time investment was around 2 hours.
Completely possible DIY project? Yup.
PS sorry for the crappy photo quality, the L100 has the worst possible screen and I can't tell what the heck is going on while operating that thing... and for the huge images-I resized them in Photobucket but they refuse to load that way once I post em.
