Roughout Leather is now available as an option for the outside of your sheath. This is the same Pueblo leather as before, just reversed to show the flesh side. This offers a more rugged look and feel, similar to what you see on a lot of work boots. Only select "custom" If your knife model is not listed, please email me to discuss sending in your knife to have a sheath custom made.
