I purchased the Craftsman 6' Butcher Block Work Surface to replace an older block and it has been nothing short of spectacular. This block is very sturdy and hasn't shown any flex or give when I placed several items weighing over hundred pounds right in the center. The top of this block has a nice smooth finish, but has enough grip that prevents items from sliding when I'm working. The bottom side of this work surface is so grippy that I contemplated on not mounting it to my rolling station. This block doesn't slide or budge an inch when I'm doing basic projects while its only being held in place by its own weight. I did eventually mount the block for an extra layer of security, but I don't feel any difference from its previous free resting setup. I would definitely recommend the Craftsman 6' Butcher Block Work Surface because it's strong, stable, doesn't require installation, clean top finish, and appears like it will last a long time.
