Shaker tradition credits Sarah “Tabitha” Babbitt with devising a circular saw for sawmill use, but the evidence does not establish that she was the first person to invent one. The story is a notable account of practical innovation; its details and priority claim need to be treated as historical attribution, not settled fact.
Who was Sarah “Tabitha” Babbitt?
Babbitt is associated with the Shaker community at Harvard, Massachusetts. Retrospective Shaker accounts identify her as “Sister Tabitha” or Sarah Babbitt, but the sources available here do not establish a complete life chronology or reliable exact birth and death dates. For that reason, precise dates should not be repeated as fact.
What does Shaker tradition say she devised?
The familiar account says Babbitt watched people sawing wood by hand and noticed that the back-and-forth motion wasted effort. She is then said to have made a notched tin disk, attached it to her spinning wheel, and tried it on shingles. The Mills Archive places the sawmill invention attributed to her at roughly 1810–1813, while explicitly noting that the attribution has been challenged and that further information is wanted (Mills Archive).
The account captures a plausible practical insight: a rotating toothed edge can keep cutting through repeated motion rather than requiring a blade to travel back and forth. But the spinning-wheel prototype and shingle test belong to the traditional story; they are not, by themselves, contemporary documentation proving that Babbitt built the first working sawmill circular saw.
#1 Best Overall
- Powerful 15-amp motor delivers 5 300-RPM for greater speed and faster cuts
- 7-1 4-inch carbide-tipped blade included. Spindle lock for easy blade changes.
- 51° bevel capacity with a positive stop at 45° for a wide variety of cuts
- Dust blower keeps line-of-cut free of sawdust for improved visibility
- Safety lock/guarded trigger and power-on indicator minimize accidental starts
Did Tabitha Babbitt invent the circular saw?
She is credited with a circular-saw design in later Shaker histories, but the first-inventor claim is unsettled. A discussion in the Ohio History Journal recounts the Shaker story and cautions that the circular-saw concept was not new, noting an earlier English example (Ohio History Journal).
Those distinctions matter. An earlier description of a circular-saw concept, a prototype, a sawmill machine in operation, and a patent are different kinds of evidence. The sources cited here do not provide a comparable, definitive chronology for those milestones, so they cannot settle who was first under each definition.

- 15% weight reduction vs. SKIL 5380, reduces user fatigue
- 51-Degree bevel with positive stops for great cut capacity
- Spindle lock for easy blade changes
- Improved dust blower keeps line of cut free of sawdust
How the story entered the historical record
The 1904 Shaker account
White and Taylor’s 1904 account of Shaker history calls Babbitt “Sister Tabitha,” credits her with a circular or “buzz” saw, and tells the notched-disk story. It also attributes cut nails to her. The book says: “At another time, she stood watching the brethren saw wood, and, remarking that half the motion was lost, the idea of a circular saw came to her.” The passage names no individual speaker, so it is evidence that the story circulated in Shaker history by 1904—not independent contemporary proof of the invention or its priority (White and Taylor, 1904).
Later popular accounts
A Museum of American Heritage exhibit repeats the claim that Babbitt invented a circular saw in 1810 and lists other inventions attributed to her. It does not provide the underlying documentation, so it shows that the account persisted in later popular retellings rather than independently confirming it (Museum of American Heritage).

Rank #3
- GRIPZONE OVERMOLD: The handles of this power tool are lined with a rubber mold. This increases friction between your hands and the tool, improving handling in most conditions
- TRANSPARENT LOWER GUARD: The polyurethane blade guard is clear, so you can get maximum visibility on your work while you make your cuts
- ADJUSTABLE BEVEL: You can adjust the foot of this cordless circular saw up to 50 degrees to cut at a variety of angles for different applications
- EXTRA SIDE HANDLE gives you improved control. Its location on the left side of the tool gives you greater visibility over your cuts while you work
- ONE+ COMPATIBLE: The circular saw works with Ryobi’s 18 Volt batteries. These battery models include the P100, P102, P103, P104, P105, P107, and P108 (Batteries not included)
What can responsibly be said about her legacy?
- Shaker tradition remembers Babbitt as a practical inventor whose observation about wasted sawing motion led to a circular-saw design.
- The notched tin disk, spinning wheel, and shingle test are memorable details from the traditional account, not conclusive evidence of priority.
- The available sources do not establish that Babbitt invented the first circular saw, nor do they settle the exact chronology of her life.
- The 1904 history also credits her with cut nails, but that claim is not independently established by the sources cited here.
The most accurate short description is that Sarah “Tabitha” Babbitt is traditionally credited with devising a circular saw for sawmill use, while the claim that she was its first inventor remains contested.
Quick Recap
Best Value
- Power corded circular saw：The corded circular saw is equipped with 4.8 Amps motor delivering a no load speed up to 4000 RPM.Compared with general mini circular saws,it has a 20% increase in cutting efficiency, which is suitable for home renovation, furniture making, and handmade projects, etc
- More precise cutting: Designs with laser guide settings and guide rails for better precision，it can help you make straighter and more precise cutting.Dust hose and adapter fits most vacuums, reducing flying wood and keeping a cleaner workspace for improved visibility
- Not just for wood: Unlike standard circular saws limited to wood, the compact circular saw has 3 blades (4½"), including TCT, HSS and diamond blades. It can cut for wood, soft metal, tile, plastic, achieving multi-material versatility and making multi-material projects simpler, safer, and more efficient. Skip the hassle of buying extra blades for unlimited projects, suitable for diy and home tasks. Good choice for DIYers who refuse to be limited by their tools
- Adjustable depth and bevel：Adjustable depth (1-11/16" at 90°) and 0-45° bevel capacity for angled cuts, you can freely adjust the cutting according to your needs. The maximum cutting depth at 90 degrees is 1-11/16", and the bevel cutting capacity at 45 degrees is 1-1/8"
- Safety and lightweight: Double switches control operation for your safety. Both the power switch and safety lock must be simultaneously pressed to start the machine. Compact circular saw weighs about 50% less than conventional 7-1/4” saws to one hand operation. The device is easy for the man, women and elderly to use
