Product title: Walnut Platter Cutting Board (Walnut, 14" x 24" x 1.25")
Product description: An all-around functional piece, the Classic Cutting board should more than satisfy everyday chopping and cutting needs. The thickness of this board provides optimal weight for cutting and maintaining structural integrity (no warping), if cared for properly. We only use the highest-quality materials and each board is inspected before leaving the shop by our top notch craftsmen and craftswomen. This is the place to buy a board that is simply unique and designed to be owned for a lifetime. Don't settle for another mass produced cutting board that will need to be replaced over and over again. A bit about our process: -- The cutting boards begin as rough lumber that is hand selected for a visually appealing and beautifully finished product. -- These select pieces of lumber are graded and then milled in order to remove defects. -- Individual pieces are then assembled using quality, time-tested construction techniques and carefully glued using waterproof glue that is FDA approved for food contact. -- Special attention is paid to edge details through a careful hand-sanding process by one of our artisans -- To bring out a beautiful shine, Howard Butcher Block conditioner is applied, which provides a durable finish and is also FDA approved for food contact. Once completed, these cutting boards exemplify the beauty of the natural raw materials found in nature, which have been hand crafted to elegantly fit the needs of everyday living.
Product feature: Walnut wood has a warm and rich chocolate hue. It is exceptionally strong, durable and beautiful.
