With modern chassis getting stronger and stronger, the older guide tongue benders just weren't cutting it anymore. We had our own made and increased the size to allow more more leverage and easier tweaking. It's made from stainless steel, and all of the hardware is stainless steel also. It comes with everything you need to use it. Just unscrew the thumb screw, place one washer on the top and bottom of the guide flag and thread the thumb screw back into the handle.
