The Craftsman Claw Flex Hammer is a two in one tool, an improved hammer and an adjustable pry bar. Light yet powerful, this tool was well thought because of its guiding system that enables you to fix a nail with only one hand, simply set the nail directly on the hammer (it stays in place because of the magnetic force) and just pound away; the pry bar may also be adjusted – it has 4 different positions – thus boosting up the leverage force you may apply on it.
