Query: Righ Tool For The Job

This tool makes downspout work much much easier and faster than trying to use plyers.There are no instructions and it's not obvious where to make the crimp or how to position the tool.I found that using it on the 4 corners of the downspout and with the side with the larger number of blades facing outward worked best.
