The picture of claw hammers shows three different sizes (and weights), from a child's size one on the left to a very heavy one on the right. The one in the middle is the one I use for most big joinery work around the workshop. The one on the right is my heaviest hammer, which I use for heavy carpentry jobs, like building flooring structures, wall frames, etc.
