This end grain cutting board is over 15" diameter and 3" thick. It will take the hardest pounding and provide a lifetime of great service. This board is kiln dried and is banded with a heavy hand forged stainless steel hoop that is driven on a 10 degree taper. This will prevent the board from splitting, even with severe use. The board is finished on the bottom and sides with a tough urethane coating and the top working surface is finished with Block Bros. cutting block oil.
