A seatbelt is a small fraction of the total cost of a car. I wouldn't be surprised if a table saw with this feature is 10x the cost of one without it or more. It adds a ton of complexity to a fairly simple tool.

At scale the cost will come down. The actual tech is remarkably simple (which is a compliment to the design and engineering). The saw blade is wired up in such a way that it becomes a capactive touch sensor. When tripped a sacrifical brake is blasted into the blade that causes it stop and drop into the table.

It isn't going to cost 10x.

  • The modules are expensive, and it destroys the blade, which can be very expensive when using real industrial ones meant to be resharpened.

    Personally I've had a very poor experience using a sawstop, as well as witnessing it cause younger guys to get overly confident

  • It's expensive because of the patent holders, not the technical complexity.

    • When the government mandates it there's no reason not to increase the price, just like how college tuitions rose exponentially when the government guaranteed the loans.

I have good news for you and your fingers. This will not increase the price of your next table saw by 10x.

It's closer to 2x the cost but that's a fairly fat margin since the Sawstop models ate the whole upper end. With a competitor they could probably get down to 1.5x.
