Yes, sorry, not trying to be pedantic or argumentative but, Nicholas' description of the process is incorrect. Not that anyone wants to be "experienced" with a Saw Stop firing but, the cartridge pops up into the blade path stopping rotation and the inertia shift causes the blade to drop. The whole thing is very anti-climactic and makes almost no noise other than a 'thunk' when heard through hearing protection with your saw and DC running. Re-use of the blade is not recommended (for the same reasons sharpeners have stopped repairing blades damaged, in almost any way, as discussed in a different thread) although it is removed from the cartridge without much fuss.
I had one firing (my fault) when I failed to notice a piece of foil tape on a piece of stock. A second firing was due to cutting some HDPE plastic that was anti-static treated and therefor conductive. In both cases the override function for a test cut would have saved the day but, I was unaware of the potential at the time. I have used the override function to test for any questionable cuts but, have never found a condition that would have caused a firing (of course when I check, I'm OK ). The first firing changed my attentiveness to foreign materials, the HDPE was just my fault for not realizing what I was cutting . . . I sure didn't save any money by scrounging that scrap HDPE to use for jig material ;-)
