I have a few nice Olivewood kitchen untensils which I adore. Rarely do I find Olivewood lumber, and usually it's quite small. What you can find readily are veneer sets. When wood is as pretty as Olivewood, usually the best stuff gets thrown on the veneer saw for maximum yield.
I guess it will be easier to find Olivewood lumber around the Mediterranean. BTW, for an Alembic neck through top, we need a board that's about 7-1/2 inches wide and 22 inches long and close to an inch thick. Set neck models and bookmatch to center options on neck throughs require wider boards.
