I am not too sure about the history of the dyed stag; I just remember when Reese sold it to me. You may ask him, I bet he remembers the knife. Not only is it rich in color, but also the stag is very dense, a great example of a Bose Knife.
Who ever dyed it knew what they were doing...I would think the “denser” the material the less it would absorb any die...but it sure did.
