Here's a great space saving idea! Our generous 20" x 14" Cherry and Walnut Large Double Cutting board comes with a second matching board which stows away inside it. The total cutting surface of the two boards is almost 4 square feet.
Rubber feet: If you select the "rubber feet" option, the inner cutting board comes supllied with one inch rubber feet. You can slide the board out halfway and cut on the inner board without it tipping or rocking, or you can pull the inner board all the way out and put it where you want. If you choose the "no rubber feet" option, the inner board comes without feet, allowing you to cut on both sides. In either case, the outer cutting board will come supplied with four small 1/4" feet.
Ken Goodwin: "The lip which holds the second cutting board in place is carved out with a coving bit, creating an inside corner that is slightly rounded, making it easy to clean."
