It's done to bend up and out of the way the rear fender well lip...which will cut your oversize tire(s). I found my car's body to not be symmetric on the frame...ie I cut the pass side MT ET Street while slowly backing out of my sloped driveway (when I gently bounced onto the street) ...but had quite a bit of clearance on the drivers side. It is not used, and am pretty sure does not work, on front fenders.
I have no pictures....thanks Nathan.
The tool should have just arrived in MA...with nobody in line behind the MA guy.
