The History of the Circular Saw: Powering the Woodworking Revolution
Early Origins: The Windmill Saw
Believe it or not, the concept of the circular saw dates back to the 16th and 17th centuries, when windmill saws were used to cut timber in Europe.
These saws were powered by windmills, which used the natural power of the wind to turn large blades, known as sails. The sails, in turn, would rotate a vertical shaft that was connected to the saw.
The saw blades used in windmill saws during this period were typically long and thin, resembling a large, narrow bandsaw blade. These blades were made from iron or steel and had teeth that were set at a specific angle to allow for efficient cutting. The blades were mounted on a frame that was attached to the vertical shaft, which would move the saw blade up and down to make the cuts.
Windmill saws were primarily used to cut softwood trees, such as pine, spruce, and fir, which were abundant in the northern regions of Europe. These saws were used to produce lumber for building homes, ships, and other structures. They were also used to produce smaller wooden items, such as barrels, furniture, and tools.
Windmill saws were very efficient, allowing for large quantities of lumber to be produced quickly and with minimal labor. They were also highly portable, as they could be dismantled and moved from one location to another as needed. This made them an essential tool for the growing economies of Europe during the 16th and 17th centuries.
Today, windmill saws are still used in some parts of the world, although they have largely been replaced by more modern sawing techniques. However, they remain an important part of the history of woodworking and industrialization.

Invention of the Portable Circular Saw
The invention of the portable circular saw is a subject of debate among historians. Some attribute it to Samuel Miller, a British inventor who patented the idea in 1777 (source: woodworkinghistory.com). However, it’s widely acknowledged that Tabitha Babbitt, a Shaker woman from Massachusetts, played a significant role in its development.
In 1813, Babbitt observed men cutting wood with a pit saw – a labor-intensive, two-person process – and conceived the idea of a spinning circular blade. She attached a circular blade to a spinning wheel, which was then powered by a water wheel. This innovation paved the way for the development of the modern circular saw. source: shakerml.org

Evolution and Widespread Adoption
The circular saw continued to evolve throughout the 19th and 20th centuries, with inventors and manufacturers introducing numerous improvements. One notable innovation came in 1923, when Edmond Michel developed the first handheld electric circular saw. His invention, known as the “Michel Electric Handsaw,”.
The Michel Electric Handsaw, also known as the “Michel Electrique,” was a handheld electric saw that was invented by Frenchman Edmond Michel in the early 20th century. The saw was designed to make cutting easier and more efficient than traditional handsaws, and it quickly gained popularity among woodworkers and builders.
From a design standpoint, the Michel Electric Handsaw was a sleek and compact tool, measuring approximately 18 inches in length and weighing around 6 pounds. It had a curved, ergonomic handle that fit comfortably in the user’s hand, and a trigger switch located on the handle allowed the user to easily turn the saw on and off.
The blade of the saw was typically made of high-speed steel and was approximately 8 inches long. It had small, sharp teeth that were designed to cut through a variety of materials, including wood, metal, and plastic. The blade was driven by an electric motor, which was located at the base of the saw and connected to the blade via a series of gears.
One of the key design features of the Michel Electric Handsaw was its ability to be used with one hand, which allowed the user to hold the material being cut with the other hand. This made the saw much more versatile than traditional handsaws, as it could be used in tight spaces and for cutting shapes and angles that would be difficult with a larger saw.
Overall, the Michel Electric Handsaw was a revolutionary tool that helped to modernize the woodworking industry. Its compact, ergonomic design and powerful electric motor made it a popular choice for professionals and DIY enthusiasts alike, and it paved the way for the development of other handheld power tools.
As electricity became more widely available, portable circular saws gained popularity among woodworkers and construction professionals alike. The convenience, speed, and precision of these tools allowed for greater efficiency and accuracy in woodworking projects, fueling the growth of the industry.

Circular Saw FAQ
1. Question: What is a circular saw used for?
Answer: A circular saw is a versatile power tool used for making straight cuts in various materials like wood, plastic, and metal. It’s commonly used in woodworking, construction, and DIY projects for tasks such as framing, cutting plywood, trimming boards, and more.
2. Question: What is the difference between a worm-drive and sidewinder circular saw?
Answer: A worm-drive circular saw features the motor positioned behind the blade, offering increased torque and cutting power. It’s ideal for heavy-duty applications and cutting through dense materials. A sidewinder circular saw, on the other hand, has the motor positioned alongside the blade, making it lighter and more compact, suitable for general-purpose cutting tasks.
3. Question: How do I choose the right circular saw blade?
Answer: To choose the right circular saw blade, consider the material you’ll be cutting and the desired finish. For rough cuts in wood, use a blade with fewer teeth (e.g., 24 teeth), while for finer cuts, opt for a blade with more teeth (e.g., 40-60 teeth). For cutting metal or masonry, choose a specialized blade made of abrasive material or carbide tips.
4. Question: Can a circular saw cut angles and bevels?
Answer: Yes, most circular saws have an adjustable base plate that allows for bevel cutting at different angles, typically ranging from 0 to 45 degrees. By tilting the base plate, you can create angled or beveled cuts in your workpiece.
5. Question: How do I maintain and clean my circular saw?
Answer: Regularly inspect the saw for damage or wear, and keep the blade sharp by replacing or sharpening it as needed. Clean the saw by removing dust and debris from the blade, motor, and vents using a brush or compressed air. Lubricate any moving parts as specified by the manufacturer.
6. Question: What safety precautions should I take when using a circular saw?
Answer: Always wear safety gear such as eye protection, hearing protection, and a dust mask. Make sure the workpiece is securely clamped or supported, and maintain a firm grip on the saw with both hands. Keep your fingers away from the blade and follow the manufacturer’s guidelines for safe operation.
7. Question: Can a circular saw cut curves or intricate shapes?
Answer: Circular saws are primarily designed for straight cuts, and attempting to cut curves may result in binding or kickback. For curved or intricate cuts, use a jigsaw or a scroll saw instead.
8. Question: How do I prevent splintering when cutting with a circular saw?
Answer: To prevent splintering, use a fine-toothed blade and apply masking tape to the cut line on your workpiece. You can also use a zero-clearance insert or cut from the backside of the material, if possible.
9. Question: Can I use a circular saw to cut through nails or screws?
Answer: While some circular saw blades are designed to cut through nails or screws, it’s best to avoid doing so if possible, as it can damage the blade or cause the saw to kickback. Remove any fasteners from your cutting path before proceeding.
10. Question: How do I adjust the cutting depth of my circular saw?
Answer: Most circular saws have a depth adjustment mechanism, typically a lever or knob located on the base plate. To adjust the cutting depth, release the lever or knob, slide the base plate to the desired position, and then lock it back in place. Ensure that the blade is set to protrude slightly below the material you’re cutting to achieve an optimal cut.
