The story of the chainsaw’s beginnings is an unexpected one. It originated as an instrument in the medical field, rather than its current industrial use. The roots of the chainsaw can be traced back to the late 18th century when two Scottish doctors, John Aitken and James Jeffray, developed the concept of a chain-driven saw to aid in medical procedures. This early version, known as the “osteotome,” laid the foundation for future chainsaw designs.
