This is a 10" thick end grain hard maple block with varnique finish.Built from select Northern hard rock maple, the butcher blocks will last for generations. They're made to professional standards by John Boos & Co., supplier to butchers, restaurants, and the White House kitchen. The end grain work surfaces are easy on knives and resist nicks and gouges. Unique features, such as the coved backsplash, are why the White House table and other John Boos products are preferred by many consultants, designers, and architects. High standards further attribute to the FDA and NSF safety listings.
