The rich, deep hues of American Walnut fashioned in a gorgeous end-grain board make for a bold presentation. Our Porter Walnut End Grain Board has all the substance of a kitchen workhorse and the beautiful patina to grace your most festive buffet or dining table. The slim profile and undercut handles make it easy to pass hors d'oeuvres or cocktails with style. Chefs choose end-grain boards because they are strong and durable, yet more forgiving on the edge of your knives. We predict this will be your go-to board for everyday use and special occasions alike, and one you'll be proud to keep out on the counter. USA Made. Lifetime Guarantee. Walnut with a teak oil finish. This board has a lifetime guarantee, but please be sure to take good care: Wash gently with warm, soapy water after each use. Do not soak your board in water or put in dishwasher. Towel dry your board after washing, and allow it to air dry thoroughly. Condition your board regularly with JK Adams Mineral Oil or Beeswax Wood Conditioner. Do not use your board in microwave.
