Testing New Table Saw Technology

Ask This Old House general contractor Tom Silva and host Kevin O’Connor look at new type of table saw with smartphone technology.


  1. Tom explains the table saw has smartphone technology. It has a feature allowing owners to program who can and who can’t use the saw. The saw can sense if the phone nearby has user clearance.
  2. Tom shows the table saw can sense moisture and drop the blade. This technology has been around, but this model uses a two-time use cartridge that pops the saw out of the way if a body part should get near it.
  3. Tom is able to reset the saw by flipping the two-time use cartridge and bringing the saw blade back to the top of the table saw.
