These cutting boards are handmade in our very own shop here in Detroit. The boards consist of Hickory and Wenge. Hickory is a wood traditionally used in cooking for its flavoring. The Wenge is used for its stability and strength functioning as a handle or place to hang the boards when not in use. The custom, hand-turned brass screws bring the two woods together in a harmonious connection built to last. These cutting boards come in two different sizes available now in our store.
