Whoa Nelly:
Now you just did open a huge can-o-worms there if that was the presumtion...

You can march out all the math in the world, and never ever prove that a Dremel is near as safe as a bench mounted buffer....
There is one huge glaring difference... the Dremel is handheld!!!!! this one fact alone makes it way, way, way, more unpredictable when being used...

I thought you where just showing that heat generation was similar or less...

Sharp metal + fast spining wheels = Dangerous stuff, period...

Now you guys that are holding the razor in one hand and the Dremel in the other, you should be on TV on one of those extreme sports things.... at least hold the edge of the razor on a surface....
