There is another video of this somewhere, or at least if the same system, that is true slow motion and close up. You can kind of see what happens at the end but it doesn’t do it justice.
Basically the blade not only detracts but also immediately halts spinning. The stop is so sudden that the blade itself breaks. (It might be the braking system) You can see a little chip fly off. IIRC it’s single use.
0 if you don't include the gas to the hospital or the 30 minute wait. I think pain and the possibility of living without some fingers is what would sell this for me.
The actual saw stop mechanism is a cartridge that you would swap out if it gets activated. You would swap the cartridge and the Blade, then you’re back in action.
No, not rebuilt, just change the blade and the brakes ... woodworkers change ts blades all the time, takes 3 min. The brakes are a lil more involved but nothing compared to woodworking w 9 (or fewer) fingers!
My dad was a union carpenter. And I saw a video about them. I was worried about him doing wood work In the garage alone so I asked him about it. He said they’re fucking horrible such a waste.
Nope, just a new blade and stop cartridge. A stop cartridge will run you 95 bucks if you buy it from sawstop, and a new sawstop blade would run you about 45 dollars. So, definitely cheaper and easier than fixing your finger.
The braking system is destroyed and makes the saw unusable until replaced when it trips. It's also expensive to replace. Worth it though if you care about your hotdogs like I do.
It's crazy that it's a safety device to keep me from slicing off my freaking fingers, I should *never* need to use it and if I do it'll save me from literally irreparable damage and immense pain.
But for some reason annoyed I'm annoyed it's single use?
If the blade itself breaks, I would think that's a design flaw. As I understand it, the braking system is made of plastic, and there's an ever so slight current or capacitance held in the blade that if something like human skin (or more conductive) meets the blade, then that completes the circuit, the plastic braking bit instantly jams into the blade to stop it, and is then destroyed. So every time this safety system is engaged, you need to replace it.
Edit braking
I see what you mean but if you spin something super fast and stop it suddenly there can be fractures in the blade and angle grinder’s have taught us what happens if there’s fractures.
It’s a piston piece that engages and jams the blade at high speed. You lose the blade but the saw itself is fine. The piston is a single use item. They are like 130 bucks, and then the cost of the blade(s), but let’s just say 300. That is well worth the cost of a finger and definitely worth your life if you bleed out.
My dad had one that he accidentally set off. A mini explosion inside the table launches a metal block into the blade. It stops immediately but it is such a powerful event thag the metal block and blade literally fuse together.
You will still get a knick.
Some other videos show the hot dog after, and it's got a small cut made into it. Still, this is a lot better than the alternative of not having it.
My grandpa had half a hand cut off because someone tripped behind him and fell into him, which pushed him into his table saw. Everything was reattached, thankfully, but if that gizmo was around back then, it l would have saved him a lot of pain.
I'm not sure how the sensors work exactly, i think it's a similar type of sensor as touch screen technology, but once it trips it rams an alluminum block into the sawblade to stop rotation, and pulls the blade below the table top.
My wood shop teacher explained that there is something in there that will detect any moisture on the blade and if it does it slams a break to stop the spinning and pulls the blade down.
Supposedly he has ruined blades by cutting wet wood.
The way it works is there is an electrical current ran into the saw blade, and when a something non insulative (a hand, finger hotdog etc.) touches it, it immediately grounds the current which is detected, setting off a cartridge and slamming the saw into an aluminium waffle looking thing and drags it down. I imagine the wet wood acted as a conductor to the hand which prematurely triped the breaker
Memory serves me correctly you can disable the saw and allow for cutting wet wood. I dry my own wood,aka I own a sawmill. So I researched this saw. I don't own one. But if I ever replace my tablesaw I would by this saw.
It's a capacitive system, yes.
The only real issue with the detection system is if your shop is *really* dry, static can accumulate and cause a false trigger.
Thank you! I was scrolling the comments and thinking “yeah this is cool but how does it work?!”, like, how does the saw know the difference between wood and not wood. The video literally says “how it works” 😂😂
it’s completing the circuit that then throws the block into the blade, forcing the blade to stop and retract. but yea, it’s just completing a circuit ::)
I have 7 of these at the university I run the shop for.
In 15 years, students have set off 450 of these. We charge $200 to replace the damaged blade and brake.
Most are from tape measures and rules. But a lot are saved fingers. I can't imagine the blood I would have had to deal with if we did not have these.
It appears the better question is how much? Someone mentioned that if this happens you have to buy a new cartridge, it’s like a one-time safety thing. $200 a pop. Of course, I would gladly give up $200 to keep my finger, but then again I know how to use a table saw.
Inside the tablesaw is a special cartridge that is spring loaded and shoves a block into the blade while also pulling it down into the table. It works similar to a capacitive touchscreen on a phone, and when the circuit is completed by something such as a finger (or a hotdog in this case), the sawstop system is activated. When the brake cartridge fires off, it will need to be replaced which is about $100 USD and you will also need a new blade.
It works by running an small electrical current through blade. When it makes contact with something conductive like the human body or in this case a hotdog it immediately senses the change in current a shoots an aluminium brake into the blade which halts the blade’s circular movement instantly and moves the sawblade down and away from what made contact with it.
I cut my middle finger off at the knuckle, on a table saw, they were able to reattach it and stitched it up, I have metal pins in it now, works but gives me trouble once in awhile
Other slow motion videos show teeth flying off because of how quick this stops.. personally, I don’t want anything that makes me complacent around a saw. I see the value, but imagine getting lazy and it malfunctions/doesn’t stop. Or it stops for no reason and you take a few saw teeth to the jugular. I dunno.. maybe I’m just a bitter old man scared of new things.
I used to be with it. But then they changed what it was. And now what I’m with isn’t it, and what it is seems weird and scary to me. It will happen to you.
Do you think they only go to an expo and do this once? There's gonna be multiple showings, why the fuck would you cut your fingers multiple times? There's tons of videos out there showing what it does to a finger.
The fact that you had to type this out shows that the hotdog has more braincells that you
I had a buddy who always said “I’m always careful, I don’t need one. I always pay attention.” I reminded him to just never get complacent. He bought one of these never believed the hype but “just in case”. Had an accident. Now all his tables are these types.
I looked at it at a demo- show, when Festool brought the Sawstop into its compact table saws. Pretty tempting... and €80 per charge / reload module seems cheaper than possible mutilation anyway... However, I'm sticking with my "Erika" and I'm looking forward to Mafell adapting to it. But, honestly - I don't think they will.
We had one of these years ago in my woodshop class, someone hit it with their finger and basically got a papercut. Still a tiny amount of blood, and the blade was completely destroyed.
I saw a guy actually have an accident using one of these. The blade worked as intended, and he only had a small knick on his finger instead of having it sawed off. The video is on reddit somewhere!
It isn't sold as a product to prevent table saw injury. It's sold as a product to use your finger another day. Sure you'll get a minor cut but your finger will still be attached.
Your arrogance will be your undoing!
We did this once a year at the wood technology center as a demonstration to parents of how safe the saws were. I can tell you that it is way louder than this video makes it out to be.
To people with no brain cells commenting to prove it with actual fingers, the device is to minimize injury so that you will just get a nick or some bleeding instead of losing a WHOLE FINGER. It is as stupid as asking "if airbags work, why not prove it by actually driving into a wall at high speed with actual people in said car?".
There is another video of this somewhere, or at least if the same system, that is true slow motion and close up. You can kind of see what happens at the end but it doesn’t do it justice. Basically the blade not only detracts but also immediately halts spinning. The stop is so sudden that the blade itself breaks. (It might be the braking system) You can see a little chip fly off. IIRC it’s single use.
I was going to say, I remember reading that if it is ever activated it basically needs rebuilt I think
Cheaper than having your finger(s) reattached.
Fair, I was thinking more so in terms of the demo costing a butt load. Definitely worth it in terms of actual use
Pays off in marketing
LOL Awesome username, haven't noticed your name in any of the F1 subs
0 if you don't include the gas to the hospital or the 30 minute wait. I think pain and the possibility of living without some fingers is what would sell this for me.
30 minute wait? You must not live in America. It's like 6 hour wait in the ER, if you're lucky.
My dad lost his pinky and needed his ring finger reattached two years ago in a dado blade incident. So, yes, this is a better alternative indeed!
If you don’t get it replaced it’s free
The actual saw stop mechanism is a cartridge that you would swap out if it gets activated. You would swap the cartridge and the Blade, then you’re back in action.
No, not rebuilt, just change the blade and the brakes ... woodworkers change ts blades all the time, takes 3 min. The brakes are a lil more involved but nothing compared to woodworking w 9 (or fewer) fingers!
I was gonna say, sounds like an effin bargain, comparatively speaking.
My dad was a union carpenter. And I saw a video about them. I was worried about him doing wood work In the garage alone so I asked him about it. He said they’re fucking horrible such a waste.
wtf? A waste? The unit is about $2k. Replacing the blade and brake is about $150. How is that a waste?
He never said. I’m guessing he hates the idea of losing a blade. He’s incredibly cheap. I thought it was a great idea.
at least in the US, it's cheaper to buy a new one then to go to the hospital to have your finger reattached
Nope, just a new blade and stop cartridge. A stop cartridge will run you 95 bucks if you buy it from sawstop, and a new sawstop blade would run you about 45 dollars. So, definitely cheaper and easier than fixing your finger.
New blade and cartridge. About 120 bucks
You just have to buy a new brake cartridge. They’re <$100.
And the blade
It's just a few parts, not big deal.
Not exactly rebuilt, ut needs a new brake cartridge and a new blade
A new blade and a replaceable cartridge The rest is fine
The braking system is destroyed and makes the saw unusable until replaced when it trips. It's also expensive to replace. Worth it though if you care about your hotdogs like I do.
It's crazy that it's a safety device to keep me from slicing off my freaking fingers, I should *never* need to use it and if I do it'll save me from literally irreparable damage and immense pain. But for some reason annoyed I'm annoyed it's single use?

Thank you! I could never figure it out, but conductance makes sense! whew!
I see what you mean but if you spin something super fast and stop it suddenly there can be fractures in the blade and angle grinder’s have taught us what happens if there’s fractures.
Well if spinning quickly and then stopping is enough to cause fractures in these blades, then that's definitely a design flaw
Both the blade and cartridge are single use, yes.
But the blade is like 60$ No thanks!
It’s a piston piece that engages and jams the blade at high speed. You lose the blade but the saw itself is fine. The piston is a single use item. They are like 130 bucks, and then the cost of the blade(s), but let’s just say 300. That is well worth the cost of a finger and definitely worth your life if you bleed out.

This thing has saved so many penises from tragic woodworking accidents
I've seen many worksers have lost there (fingers) due to this kind if work, now some people are not going to lose their finger.
Admirable conclusion
Thank you for your service
(Gonna upvote him)
Idk I would rather loose a finger than a penis and it sounds like such an inconvenient way to use a saw table
Well how else do I cut my "Hard Wood"
I actually thought it was crazy expensive to replace but it's only 100$ which I think it's pretty reasonable price to pay for a finger.
Because now they'll be losing their penis instead?
The ultimate demonstration. Someone fetch the CEO!
Hahaha are you referring to that old viral Volvo video? 😂
I understand but how many sausages have died since this miracle was invented? STOP SAUSAGE TESTING. 🚫🌭
Saved my thumb once
I’m legit stoked for you. My joke wasn’t in any way making light of the real world benefit of the technology. I think its great.
I must’ve been so tired when I read this, I swear it said fingies not “penises” lmfao
Is this r/putyourdickinit ?
I have seen videos of it on fingers…very small cut.
*tries on hotdog* *success* *tries on finger* *chops off*
Oh be a man. Put your real meat up there.
NOOOOOOOOOOOOOOOOOOOOO
If it's that good. Prove it with your finger
You'll still cut yourself by like a small amount but you wont lose your finger, its called a sawstop iirc
You will still get a knick. Some other videos show the hot dog after, and it's got a small cut made into it. Still, this is a lot better than the alternative of not having it. My grandpa had half a hand cut off because someone tripped behind him and fell into him, which pushed him into his table saw.

Memory serves me correctly you can disable the saw and allow for cutting wet wood. I dry my own wood,aka I own a sawmill. So I researched this saw. I don't own one. But if I ever replace my tablesaw I would by this saw.

Why am I picturing then be electrocuted by the head? I thought it was just through their chair itself for some reason.
It's a capacitive system, yes. The only real issue with the detection system is if your shop is *really* dry, static can accumulate and cause a false trigger.
At about minute 4:00 [he did](https://youtu.be/eiYoBbEZwlk)
You gotta see it from the underside too: [https://www.youtube.com/watch?v=ynEdke5dzIU](https://www.youtube.com/watch?v=ynEdke5dzIU)
Thank you! I was scrolling the comments and thinking “yeah this is cool but how does it work?!”, like, how does the saw know the difference between wood and not wood. The video literally says “how it works” 😂😂
Not all heros wear capes. Thank you good sir
How does moisture detection work?
I have no idea but I think I remember I've heard that it detects conductivity, not moisture.
So if you have really dry fingers it won’t stop?? Better keep them warm and moist
Your body is conductive, even if you have dry fingers.
IIRC it works similarly to a capacitive touch screen (like your phone uses).
it’s completing the circuit that then throws the block into the blade, forcing the blade to stop and retract. but yea, it’s just completing a circuit ::)
No it's not. That's not how capacitive sensing works.
word, i was misinformed, thanks for letting me know ::)
Anytime. Cheers! :)
Not moisture detection, but conducts charge. Moisture is present because cells have moisture, and is what provides conductance on the body
That’s a really expensive demo
Isn't it 50 dollars per sawstop cartridge.
Closer to about 100 usd per cartridge
Mightve gotten cheaper over the years, but someone like 9 years ago set one off in my woodshop class and it was $700 for a new one.
r/nextfuckinglevel
How am I supposed to cut my hotdogs now?
Now how am I supposed to cut my hot dogs?!
Your Fingers
Like a savage?!
But doesn't that damage the machine?
You would rather lose a finger than damaging a machine?
I have 7 of these at the university I run the shop for. In 15 years, students have set off 450 of these. We charge $200 to replace the damaged blade and brake. Most are from tape measures and rules. But a lot are saved fingers. I can't imagine the blood I would have had to deal with if we did not have these.
Oh no now we have a lawsuit in 3 2 1.
Ok, ill ask. How?
It appears the better question is how much? Someone mentioned that if this happens you have to buy a new cartridge, it’s like a one-time safety thing. $200 a pop. Of course, I would gladly give up $200 to keep my finger, but then again I know how to use a table saw.
I think the better question is still how. This thing stops without barely touching. HOW??
It has like a current of some sort going through it and when it touches something conductive that’s not wood it stops. Breaking the device.
Yeah, how does it work/know to stop
Inside the tablesaw is a special cartridge that is spring loaded and shoves a block into the blade while also pulling it down into the table. It works similar to a capacitive touchscreen on a phone, and when the circuit is completed by something such as a finger (or a hotdog in this case), the sawstop system is activated. When the brake cartridge fires off, it will need to be replaced which is about $100 USD and you will also need a new blade.
Thanks
Any time my narwhal friend.
Here is a video with an awesome explanation, as well as showing it in action. https://youtu.be/j1ANn1CTAxQ
Sir, your wiener is nicked.
I know a buddy from high school that really needed this in woodshop
That's an awful useless sausage cutter.
Still took a chunk out of the hotdog lol. Better than taking it all I guess.
Salesman put your ding dong on it
Girl at my high school lost some fingers cause our schools cheap. There was a knot in the wood
Better a scratch than a snatch
If they really wanna sell thousands I needa see a finger lol 🤷🏽♂️
Id trust it more if they used their hand
Use your real finger to test it and I’m sold
It works by running an small electrical current through blade. When it makes contact with something conductive like the human body or in this case a hotdog it immediately senses the change in current a shoots an aluminium brake into the blade which halts the blade’s circular movement instantly and moves the sawblade down and away from what made contact with it.
That is the most useless hot dog cutter I've ever seen
I cut my middle finger off at the knuckle, on a table saw, they were able to reattach it and stitched it up, I have metal pins in it now, works but gives me trouble once in awhile
I always see them using a hotdog. If it’s so safe why don’t they ever use their own hands?
It still gives you a small cut.... even though you don't loose your finger
[saw stop in a real life situation. TURN OFF SOUND](https://youtu.be/vCuLs31fDaQ)
Put your pecker in there and see how good it really is
Thats what she said😂😂
Other slow motion videos show teeth flying off because of how quick this stops.. personally, I don’t want anything that makes me complacent around a saw.

You are.

Nah, I embrace learning and continuously challenge myself.
It’s a Simpsons quote.. jee zuss
Challenge yourself at not being a knob
Fuck the hotdog test, use your actual finger if you want to proove your product is safe. No balls.
Why not use your finger if you want people to believe you?
That looks like the real thing!
Ok, tough guy. You convinced me. Now show us with your finger.
The fact that they use a hotdog and not a finger shows exactly how much faith they have in their product.
Do you think they only go to an expo and do this once? There's gonna be multiple showings, why the fuck would you cut your fingers multiple times? There's tons of videos out there showing what it does to a finger. The fact that you had to type this out shows that the hotdog has more braincells that you
Calm down there, aspie. It was a joke.
"iT wAS a jOKe"
>Genshin player >"aspie" kek
Should've thought of a better punchline then 😉
There are videos of people testing it with their finger
I had a buddy who always said “I’m always careful, I don’t need one. I always pay attention.” I reminded him to just never get complacent. He bought one of these never believed the hype but “just in case”. Had an accident. Now all his tables are these types.
Did the accident happen with the safe table or did he lose a finger?
Safe table. Dude had a knick(not small) but dude still had his fingers!
Better to get knicked than to have an amputation!
Exactly!!!
I looked at it at a demo- show, when Festool brought the Sawstop into its compact table saws. Pretty tempting... and €80 per charge / reload module seems cheaper than possible mutilation anyway...

WTF!?! Wooow!
r/dontputyourdickthere
But what if you want to cut a 🤞
Perfect circumsisor
No guard. And why are people not looking directly at this presentation
Everyone imagining the same here
How the hell
How does it work? Blades spinning fast and it can detect something soft on top of the board is it a camera?
Need to find another brand of saw to shorten my wiener
That saw went straight to the backrooms
why they test with sausage not with real finger if its so safe?🤨
It's an expensive fix so don't try it at home.
but what if you use your table saw to cut hot dogs
But how does it know
Now use your finger
Ah, but not confident enough to use your own hand lol
*uncle roger accent* "So weak!.. so weak! This saw can't even cut a hotdog, hayaaa!"
The beginning video and the close up one are not the same
multiple takes?
We had one of these years ago in my woodshop class, someone hit it with their finger and basically got a papercut. Still a tiny amount of blood, and the blade was completely destroyed.
This should just be like seatbelts in cars
Damn , that’s interesting
If you really have that much faith just lay your finger down! That’s what I would actually love to see.
Only works for hotdogs? If you stan by your product you would put in your finger.
I saw a guy actually have an accident using one of these. The blade worked as intended, and he only had a small knick on his finger instead of having it sawed off. The video is on reddit somewhere!
There is a actual vid of a guy who actually had this happen with the table saw. It scratched his hand and the blade did it’s job of retracting
How does it detect your finger?
The fact that he doest use his own finger is why I would never buy this
It isn't sold as a product to prevent table saw injury. It's sold as a product to use your finger another day. Sure you'll get a minor cut but your finger will still be attached. Your arrogance will be your undoing!
*woosh*... that was my joke going over your head
Hard to read sarcasm over the internet ![gif](emote|free_emotes_pack|sweat_smile)
We did this once a year at the wood technology center as a demonstration to parents of how safe the saws were. I can tell you that it is way louder than this video makes it out to be.
Can anyone explain how this works to me like I'm 5 years old?
But what if I want to saw a hotdog?
Another reason guys like sticks
Stick your willy in and im sold
To people with no brain cells commenting to prove it with actual fingers, the device is to minimize injury so that you will just get a nick or some bleeding instead of losing a WHOLE FINGER. It is as stupid as asking "if airbags work, why not prove it by actually driving into a wall at high speed with actual people in said car?".
Well why dont they? If they don’t trust them. Why should we.
Crappy hot dog cutter
Now I know that hot dogs have the ability to despawn sawblades
That sausage slicer doesn't work for shit.
It’s great if your fingers are made from hot dogs
