The term โcircular sawโ technically refers to any saw with a circular blade. However, we generally mean a tool like those found in our best cordless circular saw reviews. How much do you know about the circular saw โ like who invented it and the origin of the Skilsaw name and brand? We give you a โ5-minuteโ overview of the history of the circular saw.
A Brief History of Who Invented the Circular Saw
- Invented by Edmond Michel in 1923
- Joseph W. Sullivan joins Michel to make improvements on the electric handsaw and start โThe Michel Electric Handsaw Companyโ in 1924
- Originally called the โSkilsawโ
- 1926 โ Michel leaves the company, which is renamed โSKILSAW Incorporatedโ
- 1928 โ Art Emmons invents the first sidewinder circular saw for Porter-Cable
- 1937 โ Model 77 circular saw is born
- 1985 โ Patent granted to Panasonic Electric Works for a battery-powered circular saw
- 2009 โ The US Patent Office grants Milwaukee Electric Tool Company a patent for lithium-based battery packs
A 5-Minute History of Who Invented the Circular Saw
Edmond Michel developed the first electric handsaw in 1923. Teaming up with farmland developer Joseph W. Sullivan, they made improvements and started The Michel Electric Handsaw Company.
Itโs here that the handheld circular saw, as we know it, was first dubbed the โSkilsawโ. The name is so synonymous with handheld circular saws that many people still refer to any brandโs model as a Skilsaw.
Looking to pursue other inventions, Michel left his company in 1926, which was renamed SKILSAW Incorporated.
Patenting the Worm Drive Circular Saw
The patents on this original design were for a worm drive-style circular saw. In 1928, Art Emmons invented the first sidewinder-style circular saw on behalf of Porter-Cable to get around those patents. East coast and West coast construction would never agree on a circular saw style again.
Also in 1928, Skilsaw produced its Model E as diecast aluminum began to make its way into power tools to make them lighter and stronger.
The Skilsaw Model 77
By 1937, the first Skilsaw Model 77 was born โ a classic design that built the foundation of todayโs Skilsaw Model 77 circular saw.
In 1985, Panasonic Electric Works was granted a patent for a battery-powered circular saw thanks to the efforts of Hiroyuki Ando, Toshio Tanabe, and Shinji Ihara.
Ushering in the modern age of cordless circular saws, the US Patent Office granted Milwaukee Electric Tool Company a patent in 2009. The patent approved their application for lithium-based battery packs. It changed the course of cordless tool history. Milwaukee followed up with additional patents for high current draw applications (2011).
Now, nearly every major tool brand has both corded and cordless โSkilsaws,โ and lithium-ion battery technology is allowing cordless models to outperform corded.
Thatโs your 5-minute history on who invented the circular saw. Thanks for reading!
