A chainsaw has two main parts: a saw blade built into a chain, wrapped around a long metal guide bar, and a small, one-cylinder gasoline (petrol) engine (sometimes an electric motor powered by a cord or battery pack).
The first chainsaw was designed by German orthopaedist Bernhard Heine in 1830. He called it the osteotome, from the Greek osteo (bone) and tome or tomi (cut); literally, the bonecutter. This chainsaw, as well as many that followed, were used for medical purposes.
The first chainsaws were developed in the 1920's. The development of the motorised saw led to an increase in timber production comparable to that which occurred when the non motorised saw took the place of the axe. The history of forest work runs parallel to that of the human race.
