"Wow this bag of phone chargers is heavy"

on the big ones I always use my sawsall....sometimes cut down the center all the way to the "brick"...and sometimes turn it sideways and cut the whole side off (cut copper off right down side of "brick")and punch it through. It just takes a little practice like everything else and soon you'll be real fast at it. I know some like the grinder best....whatever works. Personally, I only use my grinder when I have to.....that thing is dangerous !! Wish I were more technalogically (sp?) oriented so I could make a video. Mech ???? Snodly???? Injun????
