Somewhere on this site I've seen a knife with a handle made from this wood (I think). I also think it was hardened? So.......would I be better to use wood hardener from a shop, or send it away and have it treated (impregnated?). The block in question is about 12"x3". I think it's Birch with a fungi through it or something odd.
Any ideas?
Oh I'm using it as scales, as opposed to a block.
