"If that is true, my ears must be upside down"...OR...They are the right way up, and the rest of you...
I suppose it explains why you can't get some sheets less than 2mm thick. At that thickness the decibel count goes beyond the threshold of pain and people presumably lose their hearing. Equally there are probably only so many teeth you can get on a blade, where they become useless for the job you are doing. A blade with 6000 teeth will just produce very fine dust and take three days to make a cut.
