These all-purpose boards are crosscut from fallen hardwood logs in the woods of Minnesota. Suitable for cutting or serving, the boards undergo a special curing process to prevent splitting. Unlike conventional cutting boards made from laminated wood sections, the boards are a single piece with no glue joints to separate. Finally each board is sealed with a penetrating, moisture resistant mineral oil finish, which is safe for food and which brings out the natural grain of the wood. Due to the nature (literally) of this product, all sizes are approximate, and each are approximately 1" thick. Small boards are 8"-10" in diameter and large boards are 10" or more in diameter.
