I have this wooden board that is this huge piece of a rock solid piece of some tropical wood that my father picked up at mill shop in the scrap bin. It's a solid slab of wood and has part of the outer part of the tree so one end of the short side slants for the last 3 inches to about 1" thick, so it gives a nice natural handle. It measures about 8" x 14" x 2 1/2", and after 40 years of use, looks none the worse for wear. If I knew what it was, I might get them made and sell them
