A Gorgeous but Tough Walnut Chopping Block from John Boos that's Designed for Big Food Prep Jobs

Beautiful and rugged, this versatile butcher block can handle your toughest chopping tasks or provide an elegant 12” by 12” surface for carving and serving cheese, bread or appetizers. It’s a hefty three-inch thick cutting surface constructed of premium American Black Walnut using end-grain style. End-style boards provide an extremely durable cutting surface that resists gouges and nicks, yet goes easy on knives. When a sharp knife contacts an end-grain butcher block, the wood fibers that make up the surface of the board absorb the blade, rather than blunt it. So your knives will stay sharper longer than with ordinary wood cutting boards. Plus, end-grain boards feature intriguing checkerboard patterns that show off the virtues of walnut – its rich colors and dense grain structure.

Slots for Two Cheese or Carving Knives

Whether you use this exquisite board for carving, chopping, slicing or dicing, you’ll love that it comes with dual slots for safely storing knives. No more fumbling through utensil drawers or crossing the kitchen to fetch your favorite carver from a knife block. Whenever you need it, you’ll find your knife of choice ready at your service, with its sharp edge protected, out of harm’s way.

Boos Block Board Cream with Beeswax is Pre-applied

This special formula combines mineral oil and natural beeswax to drive moisture deep into the wood, then seal it in, leaving a protective barrier that imparts a silky feel. In order to keep protect your investment, you should re-apply block oil or board cream at least monthly. If you don’t already have it on hand, you might want to add some to your order.
