Gilmer Wood, the blackwood is very nice and very hard! Worth about $100.00 if that! They prolly got them from the garbage. Same place where I get exotic cut-offs.
Go to any cabinet making
shop, I'm sure that they have more than they know what do with and will be happy to sell. Just beware some exotics are poisonous/dangerous!!! always wear gloves, watch out for splinters, fine dust. Better to be safe than sorry.
