The Bark River Adventurer II Neck Knife has great potential for neck carry. At 3.8 oz, it is well suited for it. However the sheath they give you with the knife is too heavy imho. It is really thick and has an earth magnet sewn into it, making it heavy and impractical for carry around the neck for me. So, my goal was to make a sheath for neck carry, as thin and light as possible. I wet formed it out of 6oz leather. The knife locks in and deploys like Kydex. I left part of one side of the sheath not sewn to achieve this ease of deployment, and I can easily add a stitch or two if I need to in the future to tighten it up after use, if it needs it. Right now it locks up nice, and I am satisfied that I have achieved my goal. What do you guys think. This sheath is my fourth self designed leather sheath project, and my third knife sheath. What do you think?
