🪚 Born in Blood, Raised in the Woods: The Strange Origins of the Chainsaw

From a bone-cutting surgical tool to a lumberjack’s best friend, the bizarre evolution of the chainsaw

When you hear the word chainsaw, your mind probably jumps to lumberjacks, horror films, or the unmistakable roar of a two-stroke engine. What you probably don’t think of is childbirth. And yet, the first version of the chainsaw was created not for cutting trees, but for cutting pelvises.

Yes, really.

In the late 18th century, two Scottish doctors, John Aitken and James Jeffray, found themselves grappling with a brutal problem: how to deliver babies when complications arose during labor safely.

Before C-sections were safe and common, one particularly horrifying solution was the symphysiotomy. This procedure involved slicing through the cartilage of the pelvic joint to widen the birth canal.

This procedure, performed with a knife, was time-consuming and extremely painful. So, Aitken and Jeffray invented a rotating, hand-cranked saw fitted with a delicate chain of serrated links. It looked like a modern chainsaw’s dainty ancestor, and it worked. It was certainly faster, if not any less horrifying.

Fast-forward to the early 20th century. Forestry workers frustrated with slow, back-breaking hand saws took note of this medical tool and thought, If it can cut through bone, surely it can handle oak. By the 1920s and 1930s, powered chainsaws started appearing in Germany and the U.S., with innovators like Andreas Stihl and Emil Lerp developing the gasoline-powered versions we know today.

The chainsaw’s journey from surgical table to timber yard is one of history’s strangest invention arcs. What started as a tool to help deliver babies (with minimal concern for comfort) became a staple of modern forestry, construction, and inevitably slasher movies.

So next time you hear a chainsaw fire up, remember: it wasn’t always meant for trees. Sometimes the road to innovation is messy, misguided, and quite literally gutsy.

Kevin Prince: The Inventor Who Patented the Path for Other Inventors

In a world where good ideas often get lost in red tape or buried in bad advice, Kevin Prince has spent over two decades being the rare ally who speaks both fluent inventor and fluent patent law. A registered USPTO patent agent and founder of QuickPatents LLC, Prince has made it his mission to guide independent inventors and small businesses something they rarely find: affordable, high-quality IP protection with empathy.

To date, he has assisted his client base generate 3,100 patents with 31k plus forward citations.

His journey began, fittingly, at home. Kevin’s father was an electrical engineer with 35 patents to his name, an early lesson that invention wasn’t just for lab-coated geniuses, but for anyone with a sharp mind and a screwdriver. At just 12 years old, Kevin filed his first patent, with the help of his father. From there, he headed to UC Berkeley to study industrial engineering, sharpening the tools he’d need to help others turn napkin sketches into real-world impact.

Before donning the patent agent badge, Prince was an inventor-entrepreneur himself. He co-launched a consumer electronics company, got his products into Tower Records, Hobby Lobby, and QVC, and lived the wild ride of retail success and startup struggle. That firsthand experience now powers his work with inventors, he’s not just filing applications; he’s guiding people through the same maze he once walked.

Under his leadership, QuickPatents became one of the most prolific design patent firms in the country. But for Kevin, the numbers are secondary to the mission: giving inventors a fair shot at protecting what they’ve created.

Kevin Prince doesn’t just help people navigate the patent system, he helps them believe they belong in it.

📖 On This Day in 1873: Mark Twain Patents a Self-Pasting Scrapbook

On June 24, 1873, celebrated American author and humorist Mark Twain, born Samuel Langhorne Clemens was granted U.S. Patent No. 140,245 for an innovative self-pasting scrapbook.

Frustrated by the mess of glue and paste, Twain devised a clever solution: a scrapbook with pre-gummed pages that only needed to be moistened to adhere clippings, photos, or notes. It worked like postage stamps, just add water.

U.S. Patent No. 140,245

Though better known for The Adventures of Tom Sawyer and Huckleberry Finn, Twain was also an avid inventor. His scrapbook patent became one of his most commercially successful ventures, reportedly earning him more money than some of his books.

Used widely by scrapbooking enthusiasts of the late 19th century, Twain’s invention simplified how people preserved memories, proving that even literary giants can leave their mark with scissors and glue.
