Have you seen the video demonstrations? They've been done with lunch
meat and human fingers.

17 teeth?

How fast can you push your finger?

That may be true, but they still don't do any harm.

Sawstop stops the blade in 1/200 of a second, according to their Web
site. At 3450 RPM that means the blade stops in .29 revolution, which
with a 60 tooth blade means that 17 teeth have had a shot at your
finger.

And with a 60-tooth blade spinning at 3450 RPM, that's 3450 teeth
spinning past every *second*. At that speed, coming to a dead stop after
only 17 teeth have had a chance to cut anything is pretty damn good.
Unless you're just flat-out careless or stupid (or both) and are wildly
advancing your fingers towards the blade, 17 teeth are not going to do
much damage. I could do much worse in the blink of an eye with a
careless swipe of my pocketknife.


I've seen a hotdog demonstration in which they *did* push the dog, on
top of a piece of wood, into the blade as quick as the blade with
receive it. It was much faster than anyone with any sense would advance
any stock into a table saw. The dog had the tiniest little sliver of
"skin" taken off. Had it been a finger, it would surely have bled a drop
or two. But I've done much worse to my finger when a file slipped or I
got a splinter.
