Great heavy duty tool.
I got this too for a very specific purpose and it worked great. I used it to bend and shape brass 2” X 2” “angle iron”. I used to make a lot of picture frames and this would make a great canvas stretcher.

Handles are real far apart.. feel bad for people with smaller hands if they buy these
I’m 6’5” 275lb bodybuilder that does hvac and even my hands aren’t big enough to comfortably grip around them. Well made, just wish they made the space between handle to handle where you squeeze a shorter throw. I have their crimpers no problem with those.

Broke first time using them
Terrible product, do not buy. They snapped the second i went to bend 26 gauge. Can't believe I wasted my money, honestly thought they were legit out of the box, but then they broke within 20 seconds.

Untested as of yet but these seem a little too unparallel in the jaws.
Untested as of yet, these seem a little too loose in the grip jaws. These are clearly for bending light stuff... 16 gauge or thinner sheet metal but the jaws have like a near 1/4 gap in the back of the jaws plates when clamped. Will update this post in the future based on performance.

Really like these. no complaints on this product.

The jaws are misaligned due to a bad casting job on the jaws themselves. The jaws also don't close flat/flush with eachother.
