I've actually been considering making a plain jane less expensive alternative to the usual custom sheath, but I'm still thinking about it, and then it will still probably wouldn't be quite as cheap as the production stuff.
A combat grade sheath line that is a little less expensive, without the art, but with the function, would really interest me for the SYKCO line.
But some day I will have a Rainwalker masterpiece for a special knife, I just have to decide which one.
