Why were Chainsaws Invented? Question you Probably Never thought to Ask

Get ready to have your mind blown as we unveil the mind-boggling answer to a question you probably never thought to ask: Why were chainsaws invented? Brace yourself for an incredible revelation that will leave you in awe.

The truth behind the origin of chainsaws is nothing short of shocking! In this captivating article, we will take you on a thrilling journey through time to explore the unexpected and extraordinary reasons that led to the creation of these powerful tools.

Prepare to have your mind blown as we uncover an astonishing and lesser-known chapter in the history of chainsaws. Contrary to popular belief, these powerful tools were not originally invented for cutting wood.

In a bizarre twist, the chainsaw’s humble beginnings can be traced back to its role in assisting with childbirth.

Yes, you read that right! In this article, we will delve into the intriguing story behind the early days of chainsaws and their unexpected connection to childbirth. Brace yourself for an eye-opening journey into the past!

Chainsaw a Scottish invention

John Aitken, a Scottish surgeon, is credited with inventing a chain saw-like device in 1783. His creation was primarily used for symphysiotomy, a surgical procedure performed during difficult childbirths to widen the pelvic opening. Aitken’s device consisted of a cutting chain with serrated teeth that was operated manually.

James Jeffray, another Scottish surgeon, further refined the design of the chainsaw in the early 19th century. He introduced innovations such as a chain with alternating cutting and raking teeth, resembling the modern chainsaw chain. Jeffray’s advancements in chainsaw design allowed for more effective cutting and improved performance.

While these early chainsaw-like devices were used in medical procedures, it is important to note that their purpose was specifically related to surgeries and not the widespread use of chainsaws in logging or woodworking. The chainsaws we commonly associate with those industries were developed later on, building upon the concepts introduced by Aitken and Jeffray.

To summarize:

  • The chainsaw-like devices invented by John Aitken and further refined by James Jeffray were primarily used in medical procedures, particularly symphysiotomy.
  • These early inventions were not the same as the modern chainsaws used in logging and woodworking.
  • The Scottish contributions to the development of chainsaw-like devices played a role in shaping the future advancements of chainsaw technology.

It is important to differentiate between the early medical devices and the modern chainsaws used in various industries today. The focus of this article was to address the misconception that chainsaws were specifically invented for assisting in childbirth, which is not supported by historical evidence.

Symphysiotomy: The Challenging Process of Childbirth in History

The Need for Intervention in Difficult Births: Before the advent of modern medical practices, childbirth presented immense challenges, particularly in cases where babies were obstructed in the birth canal or the pelvis was too narrow.

During such situations, a procedure known as a “symphysiotomy” was performed to create more space for the baby’s passage. This involved the removal of bone and cartilage in the pelvic region, allowing for a safer delivery.

The Grim Reality of Early Symphysiotomy Techniques

In the past, symphysiotomy was a manual procedure performed using small knives and saws. Unfortunately, the process was excruciatingly painful for women, as anesthesia was not commonly used during childbirth at that time.

This primitive approach took considerable time and often resulted in messy and distressing conditions for both the mother and the medical practitioners involved.

The Birth of the Chainsaw: Revolutionizing Symphysiotomies

Doctors Turn to Innovation: In a quest for a more efficient and less time-consuming method, two doctors invented the chainsaw in 1780 specifically to aid in symphysiotomies.

Powered by a hand crank, this early chainsaw resembled a modern-day kitchen knife with tiny teeth on a chain, forming an oval shape. Although far from the image of the chainsaws we know today, it was a significant step forward in medical technology for the time.

Expanding Usage Beyond Childbirth: The chainsaw’s usefulness in symphysiotomies soon led to its adoption in other surgical procedures involving bone cutting and amputations.

As its potential became evident, the chainsaw gradually evolved into a versatile tool that extended beyond medical applications. Its efficiency in cutting through various materials sparked interest in the woodworking industry, leading to its transformation into the powerful and iconic tool we recognize today.

From Medical Marvel to Woodworking Powerhouse

The Chainsaw’s Role in Modern Medicine: With advancements in medical technology, symphysiotomies are no longer performed in developed countries like the United States.

However, in certain “Third World” countries where access to proper operating rooms for caesarian sections may be limited, symphysiotomies are occasionally still employed as a last resort.

Chainsaws in Woodworking: Embracing Power and Efficiency: As the chainsaw’s potential for cutting through various materials became apparent, it found a new purpose in the woodworking industry.

Recognizing its ability to swiftly and effortlessly tackle tasks, people began using chainsaws for everything from tree felling and limb removal to crafting intricate wood sculptures.

The tool continued to evolve, becoming larger, more powerful, and an indispensable companion for professionals and enthusiasts in the woodworking field.

Were chainsaws truly used during childbirth?

Yes, early chainsaws were invented to assist in symphysiotomies, a surgical procedure performed to create space for the passage of a baby during difficult childbirths.

Why were chainsaws used in symphysiotomies?

Chainsaws were introduced to make the removal of pelvic bone during symphysiotomies quicker and more efficient, reducing the time and physical strain on both the patient and medical practitioners.

Are symphysiotomies still performed today?

Symphysiotomies are no longer performed in developed countries like the United States. However, in certain regions with limited access to operating rooms for caesarian sections, symphysiotomies may still be used as a last resort.


The unexpected connection between chainsaws and childbirth sheds light on the peculiar origins of this powerful tool. While chainsaws were initially developed to assist in symphysiotomies, their role quickly expanded into the realms of surgery and woodworking.

As we marvel at the modern chainsaw’s efficiency and versatility, let us reflect on its humble beginnings in the operating rooms of the past.

Chainsaws have come a long way since their unique contribution to childbirth, and today they continue to be instrumental in various industries, making our lives easier and more productive.
