No, it is NOT. It is the test for SOME types of side cutter. Other types of even the highest quality side cutters are NOT EVER tested in such a manner.
Think of taking your best pocket knife or hunting knife blade edge, and press it against hard steel, and you'll f*ck it up. Some side cutter types are not the pincer action you seem to have hard wired into your wee brain. The CUT through SOFT media. So you lost, asswipe. That is all there is to it.
