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.

I needed an easy way to flatten edges of small leather patches I was making. Leather was cut on a laser, then stamped with design. My design left a raised edge around the 400 token/patches. These worked great for flattening the edges. Very strong and good quality.

Great crisper works really well

Very nice as described on add. Thanks for a well built tool.

Good construction. I was using this to straighten out pinch welds on a vehicle.

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.

Good tool for turning hard to turn valves.

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.
