The John Boos R-Board Series 18″ x 12″ cutting board in American black walnut is edge-grain hardwood at 1.5″ thickness, 9 pounds, with recessed finger grips and flat reversible faces top and bottom. Walnut runs richer and darker than the standard maple, with a deep chocolate grain that contrasts beautifully against bright produce.
The 18×12 size suits home-kitchen counters, charcuterie service, and casual carving. Walnut is slightly softer than maple but still appropriate for daily kitchen knife work, and the darker face hides minor cosmetic marks better than the lighter species.
John Boos has produced solid-hardwood cutting boards and butcher blocks in Effingham, Illinois since 1887 — the brand that defines the American-made butcher-block category.
