The modern-day hammer has had an incredible evolution since its origins when man needed to hit and smash shells or bones to get food. Initially. I thought a post about the evolution of the hammer may be interesting, but I’ve found that hammers are much greater than just a hand tool, they are literally the great grandfather of every tool ever made!
The basics;
A hammer is a tool for striking another object or substance, whether wood, metal, stone, or anything else. The modern-day hammer has many variations, looks, and sizes. Creating an extremely versatile tool.
Then man created the hammer;
Archaeologists have now discovered the first appearance of a tool used as a hammer was 3.3 million years ago (149 found in Lake Turkana in northern Kenya in 2015) when a “hammer stone” was used to splinter more brittle stones like flint, into cutting and killing tools. After they began to perfect their technique, they formed and shaped axes, knives, then more intricate arrowheads and spearheads. Still, later these proto-humans used the formed shards into carving tools for wood, to break open animal skulls, bones, shells, and even make jewelry.
This embryonic hammer was little more than a heavy elliptical stone between 300 grams to a kilo smoothly formed at the bottom of a river bed, or from the sea. The stone was used to hit an object, which was sitting on a large flat stone below it, like an anvil. If a more intricate point was needed, the stone hammer would be replaced with a smaller stone, bones, ivory, and antlers using more finesse for finishing the new cutting tools.
Then around 30,000 BC, an incredible 3.27 million years later. The next stage of the hammer’s evolution came into being. The addition of a handle; the stone being tied to either a piece of wood or bone with leather, vine, sinew, hair or similar substance tying the head to the handle. Creating the more familiar modern-day-looking hammer, similar to those made by Native Americans in the 1800’s.
This addition may not seem a big one, but it enabled the user to have more control over what they were hitting and the accuracy of the strike. It meant that this new hammer could be used for more intricate work and meant the creation of a more artisan society. With the advent of the handle, this meant the hammers evolution to what we know today advanced exponentially. Having a handle also allowed the user to have fewer accidents with the wielded tool.
Then hammer’s next advance was the coming of metal and the bronze age. Around 3,000 BC, 27,000 years after the last important update of the hammer. Hammerheads were forged with bronze, making them more durable as far as binding them was concerned. The first hammerheads were probably melted bronze bound with similar bindings to stones and evolved with the onset of forging and casting processes. This allowed a hole to be put through the bronze to take the handle. With the invention of forges and casting other copper and bronze products were made including nails.
Bronze age hammer face. The hammer was fitted onto a piece of wood or bone, then used as a hammer.
Although iron was around in it’s raw form since the beginning of the bronze age, with meteoric iron. Which was found and used for tools such as hammers. It wasn’t until 1200 BC that iron was properly extracted and used to make tools and weapons. Making the old bronze hammers and equipment obsolete. Hammers started to evolve their shapes at this point in their history. Having round faces, square faces, cutting edges, reliefs, and so on. Among the new shapes of the hammer, the claw head was created for recovering bent or damaged nails for re-smelting. Also meaning you could reuse the precious iron or bronze nail.
The discovery of Steel was the advent of modern-day hammers and tools. From the unrecognizable embryonic elliptical stone of 3million years previously. Originally created around 1800 BC, but spread across the world properly in the 11th century. The process was refined and augmented by the 1500’s with the birth of today’s standard of steel making.
From 1500’s on the evolution of industry came the evolution of the hammer, during which the refining of hammer types and their nuances was developed and experimented with to make a different hammer that was ideal for each job. Coachbuilding, house building, bricklayers, blacksmiths, masons, miners, and any number of other jobs.
The Hammer’s produced next were “forged” by the industrial revolution starting in 1760 and 1870 the explosion in industry and the need for tools to repair and maintain the new machinery created. Also mass product of hammers, made them all similar and had to be produced to the same standards. These processes also meant that wood, rubber, copper, lead, brass, hide, and bronze hammers and mallets were easier to make and made more popular. With these new industries came bespoke hammer product such as larger moving and slogging equipment.
With the coming of the new century in the 1900’s came the invention of new materials; Bakelite, casein, and new metal alloys mean hammer faces and handles could be used in a new and different ways. With the development of physics to explain why a hammer works and man has learned to make it more efficient at its job, and so the development of the hammer has continued to become advance, along with its aesthetics. Leading to the modern hammer we see today, made by companies like Stanley, Thor and Estwing, all founded in the early 1920’s. These commercial companies essentially creating the sophisticated hammers we still see today, from the invention of massive powered steam or electric hammers to the smallest archeological or surveyor’s hammers.
