Really like that idea. Got a Ruana in the shop right now, fixing it up for a guy. The sheath isn't marked except for Ruana on the front. He'd forgotten to wipe it down after using it on a hunt and had some rusting on it. A friend had told him to soak it in a jar of CLR overnight. Don't do that. It left a diagonal line etched right across the blade and didn't do much on the rust either. Did bring out an interesting quench line though. Got er fixed u though and was able to save some of the quench line, kinda cool.
