Why Were Chainsaws Invented? The Surprising Origins and Evolution

why were chainsaws invented

The chainsaw, a ubiquitous tool in modern lumber and horror films, has an origin story that many might find surprising. While today it’s synonymous with woodcutting, its inception had a very different purpose. If you’ve ever pondered why chainsaws were originally invented for, or what they were usually used for, you’re about to uncover some enlightening facts.

The Unexpected Beginnings

Believe it or not, the chainsaw’s early ancestor wasn’t designed for lumber but rather for the field of medicine. The prototype of today’s chainsaw was a surgical instrument intended to aid in childbirth. Yes, you read that right!

The initial idea was developed in the late 18th century and was called a “trocar.” It was used to make the process of symphysiotomy – a procedure that widens the pelvis to facilitate childbirth – less arduous. This is quite the departure from what we envision when we think of chainsaws today.

The Evolution towards Lumber

It wasn’t until the 20th century that the chainsaw’s design was shifted towards cutting wood. Early wood-cutting chainsaws were bulky, large, and required multiple people to operate. However, with the rise in demand for timber, especially during and after the World Wars, there was a pressing need for more efficient wood-cutting tools. This paved the way for the transformation of the chainsaw into what we’re familiar with today.

By the 1950s, technological advancements had led to the creation of lighter, more user-friendly chainsaws that a single individual could operate. Their utility in the logging industry became undeniable.

What were Chainsaws Usually Used for?

While the primary use of chainsaws is now associated with lumber and tree felling, their versatility has allowed them to find a place in various domains:

  1. Forestry and Logging: This is the most common application. Chainsaws made the process of felling, limbing, and bucking trees exponentially faster than traditional methods.
  2. Sculpting: Artistic souls found that chainsaws could be used to sculpt intricate designs into wood, ice, and even stone, leading to the rise of chainsaw artistry.
  3. Tree Maintenance: Beyond logging, chainsaws are essential for arborists. They’re used for pruning, trimming, and removing trees, especially in urban settings.
  4. Emergency Services: In situations where obstacles or debris need to be quickly cleared, such as after natural disasters, chainsaws prove invaluable.
  5. Home and Garden: For homeowners, smaller chainsaws serve as handy tools for yard maintenance, like cutting firewood or trimming trees.

Modern Chainsaws and Innovations

Today’s chainsaws are leaps and bounds ahead of their early counterparts in terms of efficiency, safety, and versatility. Brands have integrated various features to enhance their utility:

  • Safety Measures: Modern chainsaws come with safety features like chain brakes, anti-vibration systems, and safety throttles to reduce accidents.
  • Power Varieties: Depending on the task at hand, one can choose between electric chainsaws (corded and cordless) and gas-powered ones.
  • Ergonomics: With designs tailored for comfort and reduced fatigue, contemporary chainsaws cater to prolonged usage.

Is the Evolution Complete?

The world of chainsaws continues to evolve. As with most tools, there’s an ongoing effort to make them more efficient, safer, and environmentally friendly. Battery-operated chainsaws, for instance, are gaining traction for their reduced emissions and noise.


From their unexpected beginnings in the medical field to their indispensable role in modern forestry and beyond, chainsaws have undergone a remarkable transformation. They serve as a testament to human ingenuity and the ability to adapt tools for various needs. The next time you see or use a chainsaw, you’ll have a richer appreciation for its storied past and its multifaceted applications today.
