I have purchased African ebony several times over the years. I made the stock for my wheellock from a perfectly black board, and risers for a couple of longbows too. When I worked for Robinson Firearms Mfg. here in Prince George, Don had a log of African ebony that was about 11" in diameter, and 3 1/2" long. All of the sapwood, which is white(ish) had been removed. We cut a couple of blanks from it that he turned into Mauser stocks - yikes!
My Highland pipes are made from Blackwood, as is my practice chanter. The bell split on the first one, and was replaced. It too split, and so I bought a polymer bell.
