Holy shit... that is amazing! But if anyone asks, I'm still keeping my hands in my pocket!

this guy is gonna be a millionaire, he deserves it.

Umm, true exept, look at the speed he puts hes finger in the blade. I be no1 is cutting wood with speed of 10 cm slice/day. I wouldnt trust that thing unless he would put hes whole hand there as fast as he is when hes actually cutting the wood

I would give it 2 thumbs up... if I had 2 thumbs....

@ #3 - you cut wood at various speeds. It depends on the several things like tickness, density (m3), type of wood etc. So yes sometimes you will cut very slowly and sometimes you will cut very fast.

Apart from that you kinda miss the most vital thing that actually makes this work. The reaction speed. The reaction speed is 1/1000th of a second. You can not move your hand so fast, especially not when you are pushing wood trough a saw blade. So I have no doubt his machine works.

#4 then you use another machine, change the blade, take out the security. They talk about wood not steel. And then yes you would not have the safety. But his invention just saved 10 fingers a day.

#3 If you go to the saw stop web site. You can see customer testomonials. These guys did not do it on purpose. I work around table saws every day; and there's just no substitute for common sense. Most table saw accidents are simply the result of stupidity. Still, it's an amazing invention.

The cabinet saw version of this saw (the displayed version is the less expensive contractor saw), can run up to $4000 CDN with all the options. I'd pay 10 times that to have the top of my thumb back. Accidents happen no matter how careful you are... I want one.

my only concern is that it relies on what ever part of you coming in contact with the blade being wet. which is why he put his hand in the cooler before he stuck his finger in the blade, to get it wet. it's a great idea if it can work off the water within your body, but otherwise nothing replaces common sense

#9 You are correct, it does work off the water in your body (i.e. water conducts), but the reason he put his hand in the cooler was to prevent getting any cut by making his hand more conductive. In normal circumstances you are going to get a small cut as the blade reaches for wetter sub-surface skin. A small cut is still better than seeing parts of your hand flying across the room.

I love this idea in terms of safety, and I dont want to repeat whats already been said. Really impressive bit of kit.

Ive known about these kinds of saws for years, but I didnt realise that the blade and safety mechanism has be replaced each time its triggered. If the system is triggered by accident (ie: not by someones limb), maybe by some damp wood or some containments or a short circuit somewhere, this could be quite expensive to operate. And thus not financially feasible for factories.

Perhaps it needs a little rework, where instead of stopping the blade, its just retracted at lightning speed and allowed to slow down inside the table. So you can just reset and carry on using the same blade.

Great idea and invention,

BUT

poor documentary and journalism.

They said conductivity will stop the blade.

Are conduct objects limited to human flesh only? No.

From a financial perspective,

To loose a finger costs pain, high health care costs, insurance and perhaps credit cards fees.

or void all the above for just a replacement of the blade and damaged part.

Sounds like a good trade off, but anything that is conducted under the condition that will stop the saw, will stop the saw. This opens the potential for necessary saw stops.

replace necessary with unnecessary.

cool invention

#12, they've done the research and they've got the thing tuned well enough that if you use the saw to cut wood just like it's meant to be done effectively and safely, you'll not run into any problems. We've got two of these (the cabinet model) in our shop and I love them. Not only are they safer, but they run better, are more accurate and are designed better than a lot of table saws I've used. We have had to replace the cartridges in both saws a couple of times due to tired/in-attentive people putting their fingers where they shouldn't be, but I tell you what, a $60 cart and a $75 blade are worth the finger and then some.

It scares the crap out of me when the thing goes off...it's not a pretty sound.

I got a better idea.
Worked in the cabinet business for 30 years and have all 10 fingers and toes.
Just don't stick them in TURNING BLADES!! EVER!
Works every time too.

#10 Seeing your hand fly across the room in a slow motion would be cool though!

i wouldnt go near a table saw nevermind investing in one! good piece of kit tho

Fuckin Ay! Awesome invention.

The one time the mechanism is flawed though...
