The procedure was originally performed by hand using a small knife and saw to remove the bone. This was all done without anaesthesia to a woman in the middle of giving birth. It took a long time and it was messy and obviously painful.

Now, if you’re already squirming, we’re just getting to the chainsaw part. 13th Floor enlightened us with this little-known history of this common saw. Two doctors invented the chainsaw in 1780 to make the removal of pelvic bone easier and less time-consuming during childbirth. It was powered by a hand crank and looked like a modern-day kitchen knife with little teeth on a chain that wound in an oval. We’re sure you’re envisioning those loud things that can hack up trees in seconds, but thankfully this one is a little bit less scary and looks more like a medical tool.

It then evolved into a woodworking tool when people noticed how quickly and easily it was to get through, well, anything. It became larger and more powerful and eventually grew to be the monster we know today.

Well, there you have it, the unexpected and super terrifying history of the chainsaw. Who would’ve known that the scariest power tool was originally intended for your most sensitive part?
