A buddy made these kydex sheathes for my German Army Knife and One-Handed Trekker. I can’t wait to pick them up. Retention is friction plus a kydex stud going through the thumb hole. I showed him a video of something like it and he made these. Sweet!! 33F57F7F-9E87-4FAB-ACC2-9A727E071166 by Hanzo posted Apr 7, 2018 at 11:08
