I agree that this is a very cool idea. I researched this for a possible purchase in the school I taught in 4 or 5 years back. We came to the conclusion that if you teach kids to use the saw properly they shouldn't have any danger of cutting themselves. The real danger on a table saw is kick back. I can avoid a spinning blade no problem when feeding work into a saw, but a workpiece coming back at me at 150 mph is another story. If you cut yourself on a table saw blade, you didn't follow directions. Anyone who cuts anything off on a table saw has blatently ignored directions and safety.

My favorite text book I ever taught out of said in big bold print: There is no such thing as an accident, there are however, times when people do foolish things by ignoring established protocol and common sense.

For people who have these saws... what kind of damage does the block do to the blade on the saw? Any rotational mass that goes from 6000rpm to 0 instantly would make me very nervous to re-use. That can considerably up the cost for reset.
