Edge-grain boards are made with long strips of hardwood that are bonded together to make up the larger cutting board. Due to the way they are constructed, they are susceptible to the natural warping of wood that causes these boards to pull apart. This ruins the cutting board. However, end grain cutting boards are comprised of the end cuts of a variety of woods. In a well-built end grain cutting board, that beautifully iconic “checker-board” pattern is resistant to pulling apart, giving you a stunning wood cutting board that will be passed down for generations.
