Ken- again, thanks for linking to a tool; y'all have some good equipment! (I'm still looking for the MBX wheel to be (that can be) modified for a bench grinder- something called the 'Berry Amendment' gets in the way sometimes with one of my parts sources ordering one to try out)
Recently -in my particular situation- those electric shears wouldn't have worked due to the radius of the cut out on an fender panel. They'd have been awful nice, but a set of offset left-hand snips did the trick. I do need to watch this video again to make sure it was actually 'left-hand' snips that I used...
