Our cutting boards are made of Japanese Aomori Hiba and Hinoki (Japanese Cypress wood) trees that have excellent characteristics, they are light, anti-bacterial, anti-allergic, ultra-lightweight, and anti-stain, making it a great material for cutting boards. They are durable and have a distinct fragrance similar to pine.  Popular with sushi chefs and Shun knife owners, Hinoki and Aomori Hiba cutting boards will not dull knives due to the medium-soft firmness of the wood, yet are highly resistant to water and bacteria.
