Instead, you push the lumber or other materials onto the circular saw blade to perform the cut. These are generally used in sawmills and for cutting larger materials. Next, we have the two types of handheld saw. There are smaller handheld saws that can be used single-handedly, such as the multi-tool. Alternatively, larger handheld saws have a larger motor and require two hands to operate safely.
Inventions like the multi-tool are generally for home use and smaller DIY projects. Whereas larger handheld saws are better suited for DIY workshops and construction sites. The use of saws and circular saw blades dates back to prehistoric times, although the information and reliability are not concrete.
For example, evidence has been uncovered from archaeological sites in Lothal, Gujarat. However, in this article, we concentrate on the modern history of circular saws, starting during the 18th century.
The invention of the circular saw and when it was first developed are still unclear, however. As you can see below, there are several well-known claims, and we have detailed the most prominent. What is clear is that the modern circular saw was an 18th-century invention. In the United States, the name Tabitha Babbitt is most commonly associated with the invention of circular saws.
Babbitt was a woman from Harvard, Massachusetts, and part of the Shaker religious sect. She noted how tedious and inefficient this method was and sought to make improvements. The main issue was that the blade would only cut on the forward stroke — therefore, on the return stroke, energy was wasted without any gain. As a result, one of her inventions was a notched tin blade that would operate in a rotary motion when connected to her spinning wheel.
All she would have to do is push the pedal of her spinning wheel, and the metal blade would rotate! After initial testing and trials with the spinning wheel, the inventor helped create a larger version used in their sawmill. The design caught traction and, over time, was modified and used by other communities and businesses. This versatile design is continuing to find new uses. The circular saw, mounted on a boom or on the front of a tractor-like piece of machinery, has turned tree trimming and log felling into a much safe and much more labor efficient operation.
It is clear that one of the most popular of all cutting devices is the circular saw. We use cookies to ensure you get the best experience on our website. More info Ok.

When the York Saw Works began in , our focus included machine knives, but it was saw blades that took the lead in popularity. Indeed, this was true of much of the Northeastern US at the time. Without the keen eye and inventive input of people like Samuel Miller or Tabitha Babbitt , who knows where we would be today.
