Boos Blocks are heavy duty by definition, but this 18" block weighs in at a whopping 21+ pounds! It barely fits on the kitchen counter top and certainly is not a serving block because of its heft. However, if you are looking for a serious chopping block to go in your kitchen, this is the one. The 3" thick slab of end-cut rock maple provides an ideal Heightt for cutting and chopping when placed on a standard Heightt kitchen counter. Enjoy!
