This 2-inch thick END-GRAIN solid hardwood butcher block from Ruvati is the ultimate companion for your culinary experience. Sized to fit perfectly and slide on the built-in ledges of your Ruvati workstation sinks. In dual-tier workstation sinks, it fits on both the upper and lower tiers. End-grain means the board is made of short pieces of wood standing on their end (vertically instead of sideways). This gives a beautiful checkered finish, and a cutting surface that is strong and durable. The surface is made of the fibrous ends of the wood, and with every blow the knife slide between the wood fibers. This helps keep your knives sharper and makes your chopping a pleasure. You can use this butcher block by itself on top of your counter, or if you have Ruvati workstation sink, it sits and slides conventiently on top of your sink.
