why were chainsaws invented

Chainsaws were originally invented in the late 18th century as medical tools to assist with childbirth. Scottish doctors John Aitken and James Jeffray designed a small, hand-cranked chainsaw to perform a procedure called symphysiotomy, which involved cutting bone and cartilage in the pelvis to widen the birth canal when a baby could not pass naturally. This medical chainsaw made the process quicker and more precise, although it was still risky and painful. Over time, this early medical device was adapted and evolved into the powerful chainsaws used in logging and forestry today, significantly improving the efficiency and safety of tree cutting.
