Hammers have been around in essentially the same format for an estimated 3 million years. If they’ve made it this long, why tinker with them?
But hammers are another example of a product evolving to meet the needs of its users. To the uninitiated (me), all hammers are pretty much alike. But to professionals, weight is an essential element that drives the functionality of the tool.
As contractors age, they still require the power of a heavier hammer but have a harder time yielding one on a repetitive basis. Manufacturers have noticed the change in demographics and demand and are now utilizing different materials to create lighter hammers with the strike of a heavier tool.
Even products with centuries of longevity need to change to stay relevant. Don’t assume your “hammer” will always be able to hit the nail on the head if you don’t retool and adapt to contemporary needs.
