The chainsaw, now essential in garden maintenance or forestry work, has an astonishing history dating back to the 18th century. Initially designed as a medical tool, it evolved into the versatile device we know today. This article explores the origins of this fascinating tool and why it was invented.
| Key point | Essential details |
|---|---|
| 🏥 Medical origin | Created in the 18th century to facilitate complex childbirth through a procedure called symphysiotomy. |
| 🌳 Forest evolution | Adapted to the 20th century for felling trees, revolutionizing logging work. |
| 🔧 Modernizations | Transformation into a motorized tool over the decades, offering thermal, electric and battery models. |
| 🌍 Current applications | Used in garden maintenance, pruning, wood cutting, and much more. |
| 🧠 Major inventors | Notable contributors: Bernhard Heine, Andreas Stihl, and Joseph Buford Cox. |
A surprising medical origin
The first use of the chainsaw has nothing to do with wood or the forest. Toward the end of the 18th century, two Scottish physicians, John Aitken and James Jeffray, invented a primitive chainsaw to perform a procedure called symphysiotomy. This surgical procedure consisted of cutting the pubic bone in order to enlarge the pelvis during difficult deliveries. Later, in 1830, Bernhard Heine, a German doctor, perfected this tool by transforming it into an osteotome, a bone saw operated by a crank. This invention marked a significant advance in the medical field.
However, with the introduction of cesarean section and advances in anesthesia, the medical use of these saws gradually declined in the 19th century.
Why were chainsaws invented for forestry work?
In the 1900s, the initially medical tool found a new use. Lumberjacks adapted the chainsaw to cut down trees more efficiently, particularly giant sequoias. Joseph Buford Cox and Andreas Stihl were the pioneers of this transition. They filed patents in 1925 and 1929 respectively for modern chainsaws. These innovations significantly reduced the physical effort required to cut wood, marking a turning point in the forestry industry.

Technological developments in chainsaws
Since the first models, the chainsaw has continued to modernize. The 1920s saw the emergence of electric versions, followed by gasoline models developed by Emil Lerp in 1927. Over time, chainsaws became lighter, more powerful, and easier to use. Today, they come in several types depending on needs: pruning, precision cutting, or intensive logging.
