I can't address durability as the block is a month old. The appearance is without flaw, the corners smooth and nicely rounded and the block is fully 2" thick and correctly measured in all aspects. You'll want to minimize exposure to water and treat the block with mineral oil between uses. The label says "Catskill" on it. Of the blocks I evaluated, this was clearly the most substantial and best value for the buck.
