Made in the U.S.A., the John Boos Tenmoku Cutting Board was named after an ancient tenmoku glaze used in Asian pottery. The rich brown, yellow and black colors within the American Black Walnut board have similar colors of a tenmoku pottery. The juice groove within the cutting board resembles the tenmoku tea bowls, holding the liquids until poured. Only experienced potters can hand craft perfect tenmoku pottery. Let the experienced craftsmanship at John Boos create your perfect Tenmoku cutting boards.
