Hammers haven’t changed much in hundreds of years, save a few minor tweaks with materials and aesthetics for branding.  But, though they haven’t changed, the old saying still goes, “hammers are the hammers of the construction industry.”  Don’t quote me on that. Everybody has a hammer, even people who can barely even hold a hammer.  Hammers are even used to make other hammers, here’s proof. So, when a new hammer hits the market, it’s not really that big of a deal, unless, of course, it’s the only one to provide an adjustable claw.
