It's Brazilian ebony. That's the most recognized name. I use it pretty often in cues, but not as one would think. Because it's really strong and stable, I use it in ring billets when I need a chocolate brown ring. I have also used it as cores because it has superb tonal characteristics and is very heavy, so it brightens and strengthens lightweight woods and burls. Otherwise, it's an ugly wood, IMO. It's a grainy, chocolate brown wood with no character. Smells a lot like Braz. rosewood, though, so it's pleasant to work with.
