I have been making some Custom Wet Molded Leather Sheaths for Busse knives. The largest I have made if for the Hognose War Sword and the BB13. My wet molding process offers excellent retention and a perfect fit with a light weight that is typically around half the weight of a similar Kydek sheath with belt clip. The huge Hognose War Sword sheath weighs in at 6.5 ounces and the Mini Mean Street sheath weighs in at less than 1 ounce. Made from 6oz veg tanned leather. Built in belt loop for a 1 1/2" belt. Very low profile and compact sheath to carry on your belt on stow in your pack.
