People often mistake things I make from Black Acacia for the much more famous Hawaiian Koa. Koa is a member of the acacia family and the wood is very similar. In fact I don't know enough about them to distinguish one from the other. The Black Acacia I know came from Berkeley California where it was planted sometime in the 1920's to enhance the landscape and provide shade to many of the craftsman style houses. They say it came from Australia...maybe with a layover in Hawaii?
