I had a customer wanting the "Boomerang" I had done previously with ancient red gum and some buck eye burl. The red gum wasn't a problem but SOL on the buck eye, so I went through my knife scale suppliers offerings and found some spalted Tamarind. Not quite buck eye but came out better than I had hoped for. More importantly she's happy with it too. Just in case it didn't work out I did one with some redgum burl.
