We sell a lot of butterfly knives, however not many of them come with their own sheaths and we don’t offer separate sheaths for them… until now. The Calm for Now Butterfly Knife Holster is finally here. With sturdy ABS construction, small 3.5-inch length, and black color this holster is the best friend of all butterfly knives. The screws you see on the left side of the front mean that this holster offers adjustable retention, which means you can loosen it if your butterfly knife is too thick for it when you get it. A belt loop is built onto the back of the holster for secure carry. The butterfly knife is closed and inserted into the holster with the handles sticking out so you can unholster the butterfly knife quickly and easily. The Calm for Now Butterfly Knife Holster ensures your butterfly knife will stay calm… for now. Overall Length: 3.5 Inches. Weight: 0.1 lbs.
