Okay, I watched the video and all I could say was "WOW!". This saw is
probably fairly expensive. Besides, I have a nice one and am always
very careful.

But it only takes one mistake to lose a finger. Click on the link and
watch the videos linked on the site. It's amazing. I have to ask - is
this for real or is this some kind of high tech joke?

Has anyone else seen this machine before?
