By putting this item in your cart ALONG WITH one of our standard knife blocks, we'll add a cleaver slot to your knife block! You can see a great example of this cleaver slot on the pictured walnut knife block. This block has been stained dark to match a walnut butcher block, walnut knife blocks tend to be lighter in color than this one. Since we have to make your knife block to order to add the cleaver slot, it will take approx. two weeks to ship once you order. Thanks for your patience!
