This board is a one of a kind! The ripple effect is a natural part of the tree, called "crotch grain". The way it shimmers in the light is truly amazing! Made of beautiful black walnut, it's cut in to a paddle for effortless serving and can be hung for storage/display when not in use. The board is 5/8" thick, 6" by 17" at it's longest point of the serving area. Every board purchase comes with a complimentary tin of our homemade board butter and care instructions.
