I searched UL.com and found a "sharp edge tester."

The 2005 NEC includes some references concerning sharp edges too.

Have you ever cut your skin when working on older equipment where the original paint has worn away?

I have on cabinet covers, have scars too prove it.

What should be done about this, get everyone a "sharp edge tester?"
