It has a pocket in the front for a sharpening stone. On the side, it has a ferro rod to start fires. It's for bushcrafting mainly. I know it's a little rough around the edges and my stitches aren't perfect, but it works!
That's awesome, I have a knife that could use a sheath like this. It has a very minimal sheath right now and the knife likes to fall right our everyonce in a while when on my belt. I would love to carry a sharpening stone with me.
