Thats true.. I could have ten sets of glasses or goggles next to me and i wouldnt have used them (before)..... My pops would be yellin and cussing.. Calling me stooopid, if i was doing something dangerous... Maybe wear goggles and a face shield :D ?? Well i was talkin bout an milwuakee 4 1/2" angle grinder, with a 5/8" shaft and a wire brush , the kind thats shaped like a cup?
