This bamboo carving board by Shun Gourmet Cutlery has a large 24" x 14" oval surface area that allows plenty of room to work and a grooved border channel that retains juices. Bamboo is harder than maple and doesn't absorb moisture, ensuring that your board will maintain its shape with washing, time and time again. The natural hardness helps it resist knife marks and retain its beautiful appearance even under consistent use. Bamboo is also a safe, sustainable and an environmentally sound choice. 1 1/2" thick
