I was in the shop today and had some kydex "scraps". I really hate waste and started thinking about what I could do with these long and thin pieces of kydex. Next thing I knew I had a handy neck sheath for the Victorinox Paring Knife that I use in the shop. I put the knife under a drill press and added a lanyard hole and the result was a knife that could go in a survival kit that weighs next to nothing.
My SAK blades have always taken a razor edge and I've had the same luck with the paring knives.
I can take and post some pics tomorrow.
