Crutch--
The only reason I referred to Grady is because he became something of the "go to" among RMK people.
I try to avoid adding anything to a sheath that might soften it. It is not nearly as protective against cut-through if it is weakened, soggy, limp.
The sheath in this thread looks pretty good, maybe a bit of cleaning to the surface and maybe a coat of wax to seal the smooth surfaces. Do nothing to the rough leather.
I am trying to renovate a Seguine sheath currently that got something put into it that softened it a bit as far as I can tell. Cleaned it, now letting it fully dry in the "warm" garage, then just a good coat of paste wax on it to seal it and hopefully firm it up a bit.
