Chainsaws were originally invented as surgical tools to cut bone and tissue during difficult childbirth and other operations, not for cutting wood or trees.

Quick Scoop

In the late 18th century, early chainsaw-like devices were developed by doctors to speed up procedures such as symphysiotomies, where bone and cartilage in the pelvis were cut to widen the birth canal when a baby was stuck. These tools used a hand‑cranked chain with small teeth to saw through bone more quickly and precisely than manual knives and saws.

Over time, similar chain‑and‑tooth mechanisms were adapted for orthopedic surgery and bone removal beyond childbirth. Only later, in the late 19th and early 20th centuries, engineers and loggers adapted the same basic idea into larger, powered machines for felling trees and cutting timber, which is how chainsaws became associated with forestry and logging today.
