Actually, the first gas-powered chainsaw was invented in 1927. Before that, the idea of the chainsaw dates back to the late 18th century when John Aitken and James Jeffray, two Scottish doctors, tried to develop a new medical tool to cut bone and cartilage (so, basically, chainsaws were first used to cut flesh and then became widespread lumber and construction tools).
