Chisel



Tools can tell us a great deal about the society that made them. The more advanced a society, the more it produces, and the more tools it uses. The story isn't one of continual development as there are periods when progress is slow or even goes backwards. This timeline focuses on the chisel and it’s adaptations indifferent time periods and cultures.


The Neanderthals developed the first chisels out of stone, the most easily foundand shaped material at the time.


Egyptians and Romans both developed copper chisels to be used with mallets to shape stone for building and sculpting.

Medieval craftsmen fashioned chisels outof iron to use in working with woodfor furniture.


In the 19th century, wood workers began using steel and other highly durable materials to maximize the sharp edge and minimize wear.


Modern jackhammers utilize the chisel wedge, along with a pneumatic power source to break
thick and heavy surfaces quickly.
