An indispensable device of freedom, the chainsaw has debated origins that included a cringeworthy use
Many info sources agree that chainsaws had been invented to be used not by lumberjacks, however by—eew!—medical doctors.

He was distracted whereas peeling the Christmas wrapping paper from the square-ish field, his eyes and a spotlight targeted on one other dialog throughout the lounge. However when he seemed down and realized what he had in his palms, it was powerfully apparent that my brother was reveling in an excellent current for his current and future.
A Stihl 180 chainsaw is not only one other reward while you treasure your time outdoor and have a T-shirt that claims 9.2—the variety of tree-laden acres your land occupies. It turns into a reliable, important companion that shapes this more and more messy world in exactly the methods you select.
Lower than a 12 months later, tons of of miles to the southeast in Greenwood, S.C., the authoritative whrrrrr of chainsaws took on a special sort of significance for me.
When Hurricane Helene unleashed its lethal torrents of wind and rain on my hometown on September 27, dropping numerous towering timber onto roads and homes like so many toothpicks, chainsaws had been indispensable instruments of freedom for these trapped of their properties and in any other case hemmed in by nature’s fury.
This obtained me enthusiastic about how these mainstays of the forestry trade—paradoxically, able to inflicting their very own sudden destruction—got here to be. They’re primarily easy machines that include an engine, drive mechanism, information bar, slicing chain, tensioning mechanism and security options.
However figuring out their origins is something however easy when researching on-line, the place solutions are as scattered as tree limbs on a hurricane plain.
Lesser-known claims
The primary working prototype for a chainsaw, powered by a hand crank, was developed within the 1400s by German navy engineer Konrad Kyeser, in accordance with The Enlightened Mindset—which claims to be the “world’s first totally AI-generated web site.” Whether or not this purported first provides to or subtracts from the credibility of its info is as much as the reader.
Sawtheory.com says the chainsaw was invented within the early 1800s by German blacksmith Konrad Borchardt. “The unique design was used to chop down timber and had a noticed mounted on lengthy handles with two steel arms related by hyperlinks, resembling a series,” the positioning says.
Alas, the positioning additionally says, “The primary patent for a mechanical noticed was granted in 1830 to a German inventor named Andreas Stihl” —which might be an unprecedented feat, provided that Stihl was born in 1896.
Sawtheory claims the chainsaw as we all know it right now was invented in 1918 by Canadian engineers Joseph Buford Cox and James Shand. (We may discover no different supply crediting them for this.) Reportedly, their unique design featured an inside combustion engine hooked up to an extended bar with enamel alongside its edge.
The unkindest reduce of all?
Most info sources agree that chainsaws had been invented to be used not by lumberjacks, however by—eew!—medical doctors.
Based on BBC Science Focus, their goal was to extra seamlessly take away diseased bone and even “reduce away flesh, cartilage, and bone from the mom throughout childbirth if the newborn grew to become caught within the start canal.”
BBC Science Focus cites Scottish medical doctors John Aitken and James Jeffray as inventors of this versatile however crude noticed; This Week in Libraries journal agrees. In style Mechanics no less than partially helps this notion, reporting that in 1785, a series handsaw mannequin appeared in Aitken’s Rules of Midwifery, or Puerperal Drugs and describing a course of whereby a “serrated chain is used to take away diseased bone.”
The versatile noticed later grew to become the osteotome, developed by German doctor Bernhard Heine in 1830.
Allthatsinteresting.com, apparently sufficient, makes no point out of Drs. Aitken and Jeffray. Nevertheless it supplies spectacular element about Heine’s noticed:
“Heine added guards on the perimeters of the chain to guard the encircling tissue, so surgeons may now reduce into the cranium with out inflicting bone splinters or destroying tender tissue. It vastly improved any medical process that required slicing by bone, similar to Nineteenth-century amputations.
“Earlier than the chain osteotome, surgeons used a hammer and chisel to take off a limb. Alternatively, they may use an amputation noticed that required jarring motions. The medical chainsaw simplified the process and improved outcomes.”
Heine’s design earned him worldwide acclaim. Producers in France and New York started making the surgical instrument in mass portions.
‘Infinite’ impression
Finally, an inventor found {that a} chainsaw may rip by a redwood tree even higher than it may reduce by human bone.
In 1903, San Francisco logger Samuel J. Bens utilized for a patent for his “endless-chain noticed” with a looping chain that he stated was primarily based on Heine’s osteotome. His 1905 patent is taken into account the primary for an electrical chainsaw. (Allthatsinteresting.com calls Bens’ conception “the primary recognizably trendy chainsaw,” an clearly subjective proclamation.)
What can’t be argued is that these early chainsaws had been massive and heavy sufficient to warrant use by no less than two individuals.
In 1926, the aforementioned inventor Andreas Stihl patented the “Cutoff Chainsaw for Electrical Energy,” weighing in at a whopping 116 kilos. As a result of it’s usually acknowledged as the primary electrical chainsaw on the earth and led to an organization that continues to be a frontrunner out there right now, Andreas Stihl has the fascinating unofficial title “Father of the Chainsaw.”
Chainsaw Daddy revolutionized the lumber and logging industries with a machine that simply reduce down timber with precision. This additionally led to the event of recent woodworking and building practices.
Finally, the event of lighter aluminum alloys and cast metal elements helped facilitate one-person, transportable saws. Different enhancements adopted.
Stockholm-based Husqvarna launched its first chainsaw, the Husqvarna 90, in 1959. It featured mufflers that the corporate claimed decreased noise ranges by one hundred pc. 5 years later, Stihl launched the primary anti-vibration deal with that used buffer parts to soak up vibration from the blade and engine.
Newer innovation contains the development from gas-powered to electrical chainsaws, and now chainsaws powered by lithium-ion batteries.
The most recent applied sciences embrace laser-guided slicing and computerized blade sharpening—all a part of a centuries-old evolution that’s more and more innovative.
Patent Pathway
Samuel J. Bens utilized for the primary patent for an electrical chainsaw on July 17, 1903. The assignee was John S. Kimball. U.S. Patent No. 780,476 was granted on January 17, 1905.
Bens wrote in his software: “My invention pertains to saws, and my object is to supply a noticed tailored for common use, and notably to crosscut-sawing, for which these days hand-operated saws are nearly universally employed.”
A Delusion and a File, Massacred
- The slasher cult movie “The Texas Chainsaw Bloodbath”—impressed by a real story that didn’t contain Texas, chainsaws, or massacres—premiered on October 1, 1974. Actor John Larroquette has stated he narrated the prologue of the film (price range: $140,000) in change for marijuana.
- In 2011, Canadian Ian Stewart broke the Guinness World File when he made 94 catches whereas juggling three lively chainsaws.
Chain of Destruction
Ten days following Hurricane Helene, greater than 220 storm-related deaths had been reported.
The hurricane’s wind and rain destruction lined 600 miles.
Hurricane Helene and different storms dumped 40 trillion gallons of rain on the South, from Florida’s Gulf Coast to Tennessee.
