I was assuming it was cocobolo without the streaking I've seen in other examples (wood is actually less red than it shows in the photo--more orangeish). Also assumed it wouldn't be padauk because the wood came from a thrift store as part of a laminated cutting board, & I always thought padauk was much more expensive than coco, so unlikely to be in a cutting board.
The wood really has open grain, larger pores than walnut.
