Sheath looks good to me. Did you just melt the candles and paint and hairdryer it into the leather?

I hot dipped my SBT knife sheath in molten paraffin, then molded it around my knife handle (I wrapped the handle in 3 layers of wax paper to shim it a bit). It is hard as iron now and the handle "clicks" into the sheath. No way it is coming out unless I want it out.
