There are few Kydex Benders that are more forward-thinking and self-defense oriented than Dark Star Gear. Their holsters are excellent and their knife sheaths don’t get nearly as much attention as they should. If you have a fixed blade that is worth carrying, they can make a sheath that will offer excellent retention and access.
When it comes to carrying a fixed blade knife for self-defense, they really know their stuff which is why this recent image that they posted just about sent coffee out my nose. It’s funny but this particularly sensitive region is also a very viable target.
