History
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 arrow heads and spear heads. Still later these proto-humans used the formed shards into carving tools for wood, to break open animal skulls, bones, shells and even make jewellery.1
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.1
