But have you ever given any thought to how or where the ability to gather such a large quantity of wood originated? Would you believe me if I told you that it came form the jawbone of an animal?Some four thousand years ago the interest in woodwork was increasing.

Around this time the discovery of copper allowed for the invention of a tool, the saw, that could fulfill this need. This saw was designed with a thin piece of copper stuck into a small piece of wood. The copper strip had teeth lined up along one end that allowed the tool to cut a kerf in a small piece of wood. They later replaced the copper with bronze, and the bronze with iron. This new saw was effective, but was not very specialized. It would react differently under different conditions. Eventually more complex designs were discovered. These new designs allowed for the precision cutting of hardwood, softwood, with the grain, against the grain, and even raked out the unwanted sawdust. These saws differed in the layout of the teeth. Instead of the jawbone patter the teeth were placed in a "left-right-angled" pattern, to rake the sawdust, and were placed at different distances depending on the substance being cut.Honeycutt 2As these handsaws progressed and continued to make the job of the wood worker less difficult logger began to take interest in the idea of a saw. This led to the invention of the large two-handled tree saw, which replaced the ax. This saw was made so that two men operated it, one on each side of the tree. The saw was designed to where it had teeth cutting in both directions. This almost doubl...
