This saw stops as soon as it detects a finger on the blade, fast enough so that absolutely no injury is sustained.

I have seen them and one is on my list of shopping for my shop. When activated it does destroy a stop block. You have to replace that but it is a small price to pay to keep all your digits. Woodcrafters had them the last time I was in their store in Boise. I assume they are in all their stores now. I am a real believer in their technology.

Brilliant!
Pretty awesome.. I just wonder how often it accidentally trips because of moisture in the wood, nails, etc? I know a guy who lost a thumb to his table saw. Not fun. I often think of him when I'm ripping wood..

There's a switch you can shut-off the sensor for those type of cuts.

Good idea, it may save you the same fate.
The reviews I've read say it's a nice saw, a lot of money but .............
The best piece of safety equipment is between yer ears, IF it seems unsafe , it MTL is. Stop,,,,,,,,, re-think it , add a hold down , get the push stick , one or two should always be with in reach ,or some such.
I'm with PEG. There are so many things to get hurt on if you are careless that a good head with full mental faculties is hard to beat.
Like - the saw saved my thumb just so I could shoot a nail through it... [waiting]
In my experience , substance abuse has caused more injuries to workers than injuries to someone who could think clearly.
My simple rule is to never get my hands within 12" of the blade . . . I use a number of push sticks-blocks and on larger pieces, such as plywood, I use a wood handle rubber concrete float.
Be carefull with push sticks. The saw blade could catch the wood, spinning it off the table.

A table saw "sled" is also a good addition to the table saw . . .

We have had one at work for probably 5 years. The decision was made after we had a guy loose 3 fingers in one fail swoop. About a year ago one of the guys came into the office and said I was going to be mad at him for setting the saw off and I said why and he showed me his thumb. Half way up his thumb was a nick which surely would have been an amputation and all that was needed was a badage.
The saw will activate with wet wood or any metal contact but this can be bypassed. The blade generally needs replacing after it has gone off as well as a new brake cartridge, all told $100.00 with an inexpensive blade.
From a safety standpoint it is an excellent piece of equipment because most people, including many who have operated a table saw for years, dont realize how dangerous it is until it throws something at you or cuts fingers off.
They have a new contractor saw which is more reasonably priced. It really makes me think when I use the old Delta at home what can happen in just a second. It is worth the money.
If you have anyone who works for you, the sawstop is probably a fantastic purchase from a liability standpoint. The technology is pretty failproof. It senses electrical conductivity to trigger. Moisture wouldn't trigger it. Metal would (there is a defeat switch)... Human skin would. It's about $80 to replace the unit that triggers if it does + the price of the blade. In my opinion, there is no substitute for safety. But the extra $1200 for the sawstop saw is a couple of extra tools you COULD buy.
It is a well designed saw though.
I may buy one someday. I'll use the money that I save by refusing to buy a pneumatic nailer.
Double safe!
actually had fundraiser lunch with the owner a few months ago...very nice, and we discussed several additional applications. Based on a constant ground electrical loop. Moist lumber/nails/etc have no effect, but human touch will stop it dead in something like 1/1000th of a sec.
