Can I use a coated blade on a SawStop saw?
However, most coated blades do not cover the blade teeth. Those blades may be used on SawStop saws. Further, blades with depth-limiting shoulders may take longer to stop in the event of an accident than standard blades, and you could receive a more serious injury. Therefore, SawStop recommends using blades without depth-limiting shoulders.
Do you have to wear gloves when using a SawStop saw?
Do not wear gloves when using a SawStop saw because the glove can snag on the blade and pull your hand into the blade at high velocity. The safety system will still react as soon as your skin contacts the blade, but the resulting injury can be more severe because of the velocity of your hand.
Why can't you cut your finger on a SawStop table saw?
The SawStop senses an electrical current in the hot dog. Gass induced a very weak electrical current onto the blade of the saw. He put an inexpensive little sensing device inside it. And if the saw nicks a finger, within 3/1000ths of a second, it fires a brake that stops the blade.
Are SawStop blades any good?

Will wet wood trip a SawStop?

When was Sawstop invented?
SawStop, at the time consisting of "three guys out of a barn in Wilsonville ", demonstrated a prototype in August 2000 at the International Woodworking Machinery and Furniture Supply Fair trade show. A series of meetings followed, in which Gass "negotiated with major players such as Ryobi, Delta, Black & Decker, Emerson, and Craftsman " in an attempt to license his invention; he followed those negotiations with a February 2001 presentation to the Defense Research Industry, a trade group for attorneys representing the power-tool industry. That presentation immediately preceded one from Dan Lanier, Black & Decker's national coordinating counsel; Lanier's presentation gave Gass the impression he was unlikely to succeed in convincing major power tool manufacturers to license SawStop technology.
Where is Sawstop made?
SawStop is a table saw manufacturer headquartered in Tualatin, Oregon, US. The company was founded in 2000 to sell table saws that feature a patented automatic braking system that stops the blade upon contact with skin or flesh.
When did Sawstop come to Ryobi?
In January 2002, SawStop appeared to come close to a licensing agreement with Ryobi, who agreed to terms that involved no up-front fee and a 3% royalty based on the wholesale price of all saws sold with SawStop's technology; the royalty would grow to 8% if most of the industry also licensed the technology. According to Gass, when a typographical error in the contract had not been resolved after six months of negotiations, Gass gave up on the effort in mid-2002. Subsequent licensing negotiations were deadlocked when the manufacturers insisted that Gass should "indemnify them against any lawsuit if SawStop malfunctioned"; Gass refused because he would not be manufacturing the saws.
When did the CPSC hold a hearing on table saw safety?
On August 9, 2017 , the Consumer Product Safety Commission (CPSC) again held hearings on table saw safety. Despite statements made by the saw industry claiming they are making their saws safer, without resorting to a finger detection technology, injuries and amputations continue to rise, and now stand at over 4000 per year.
Who sued Ryobi?
Gass served as an expert trial witness in 2006 when Carlos Osorio sued Ryobi for injuries sustained when he was injured using a Ryobi table saw. Osorio claimed the saw could have been made safer if it had used Gass's invention. Gass also worked with plaintiffs on other table saw lawsuits.

I was crosscutting a 1/2 inch piece of Baltic Birch plywood on my SawStop contractor saw last weekend when my brake went off. No part of me was near the blade, and the only irregular thing was that I was cutting a 45 degree bevel for a box. As expected, the blade was ruined.
wdwerker
If the blade flexed and hit the throat plate that might have caused it. Nice to hear that they respond.
Chet
I don't know if they still do, but if the activation was from a flesh strike, which your's isn't, SawStop would replace the brake for free in exchange for the spent one so they could analyze activation of the brake.
BonPacific
That's cool, a handy black box. Shows some dedication to improving the tech too. I wouldn't say it's quite a big-brother situation since you have to willingly send them the brake.
Marmotjr
Betcha it's a holdover from their R&D days. I would bet while developing the tech, they had a few misfires (for the reasons listed above), and they needed to trouble shoot the issue. So they probably added a chip that can store to EEPROM and it would store the voltages or what nots that trigger the brake.
minorhero
I used to belong to a club shop that also sold SawStop. I will say that the chip in the break is marketed as a feature. Probably the most common question people have concerns break activation and conditions for misfires.

Is the brake going off a changing pants moment or do you stand there for a while wondering what just happened?
