I sent a PM to Rainwalker the other day about his thoughts for an ankle sheath for Uncle Um. He said he has made them before and would give it some thought. I am wanting a good minimal (for concealability) sheath. I would LIKE leather, but don't know how leather would hold up. It needs to be secure enought that If I get into another scuffle in the jail I woldn't have to worry about it coming out and an inmate picking it up.
