HURRICANE 3inch Sheet Metal Hand Seamer, Heavy Duty Bender for Metal Flattening, Precision Duckbill Pliers and Sheet Metal Tongs, Ideal for HVAC Projects, Ergonomic Straight Flat Smooth Jaw

Very nice tool. Sturdy and well-made. The jaws are 1 inch with 1/4” guide markers on each side to enable an even crimp. I have bent, aluminum, flashing, hardware, cloth, and windows screen. This still worked well on all these materials. Will be trying 22 gauge copper next. I will update this review if the tool does not work for that gauge. I am a 73 year-old handy-woman with arthritis in my hands. This tool was not a problem to use. Well designed grip helped with leverage.

Great crisper works really well

Powerful, nice constructionCan be used in defense against very slow butterfliesNot big enough to crimp a finger, so you are either safe, or disappointed. My Uncle Scooch was looking for something that could open enough for a thumb, he did grin when he felt how heavy it was.But for me, using it for its intended purpose, it is a very good tool.

Worked good , got the job done easily !!

This tool was super helpful. Nailed it for the project purposes I bought it for. But then its also come in handy numerous times sense just being a handy tool to have. Whether its to actually brand or to just hold something else you are working on.

Perfect for finish panel work on Aircraft cowling I am creating from scratch - no marks to clean up just nice tight panel edges...Two Thumbs Up!! -- Highly Recommend Buy!!

The tool works well, but the design of the lock to keep it in closed position is poor. The lock lever bears against one of the sides of a hex head bolt which connects the handle to the jaw. If the bolt rotates even slightly as the tool is used the lock will not engage until the bolt is rotated slightly. This requires using pliers to rotate it, and this happens almost every time I use it.
