Brilliant! Now that's what I call an useful invention.

Surely it's easier to remove remove skin from a hot-dog by nicking it with
a stanley knife :-P

Actually I think that's done the rounds here a while back, but last time
it didn't show the internal workings, looks like it has some explosive
charge to drive the jammer into the teeth? Presumably not cheap to reset
after "use", but cheaper than microsurgery eh?

According to the one of the videos you just replace the blade and the
aluminium (sorry, aluminum as its a Merkin thing) jamming mechanism which is
a replaceable cartridge which takes about 5 minutes. The "exposive" doesn't
drive but releases the catch - the jammer is held back against a strong
spring in use. The angular momentum transfers to the blade arm assembly
instantly as well, so the whole thing has no choice but to swing down.

My worry from the employer's point of view is that, should one fail to
operate and a finger is lost, the employer would then be liable as the
safety device was expected to be there, rather than if it were not fitted.
Still 60,0000 table saw accidents a year is a lot of fingers!
