Additionally, you’ll find common information about this type of blade below. Such as what characterizes it and how it works.

What is a circular saw?

Specifically, it is a power saw employing an abrasive or toothed disc rapidly rotating around an arbor.

How do circular saw blades work?

Each “tooth” of the blade removes a chip of your material to reveal the overall grind cut, one small piece at a time.


While there’s no official origin for circular saw blades, there are plenty of claims of how they came to exist. The most recognized legend is their appearance in the patented saw windmill of English sailmaker Samuel Miller in the late 18th century. However, our particular favorite is perhaps the myth of its creation in a Massachusetts Shaker community by Tabitha Babbitt. Though it’s generally considered discredited given the lack of historical documentation. Regardless of the who, where, and exactly when, these blades were completely popularized in the U.S. by the mid-1800’s thanks to the lumber industry.

    I want to rip down a piece of Lignam Vitae (36″ to 42″ length), but 1.5″ square. Yield would be four lengths of walking cane stock, 3/4″ square less kerf wastage. I could go to a local woodwoking school shop, buy them a blade, or set up a jig to run a 7 1/4″ circular saw blade along. Forums keep talking about scrap wood for a jig, but at the cost of Lignam Vitae, some very decent hard maple would probably be better.
    Given that, is there a blade that would produce less kerf, smooth cut, and wouldn’t tear itself apart on the Lignam Vitae?
    When I get back from Maine, I’m close to your location in Philly.

      Hey Jeff,

      We haven’t done much work with Lignum Vitae. However, knowing that it’s very dense and hard, one of the best table saw blades we’ve used with a thin kerf is the Forrest Woodworker II 40 Tooth ATB – 1/8″ Kerf (#604-1040). We might also recommend trying the Woodworker I 60 Tooth ATB – 3/32″ Kerf (#604-1060, same page).

      And of course, let us know if you have any questions about the blades!
