Hello everyone! Been a while!
I was given this by a friend. It was pretty locked up, so I've freed most of it, but I'm not exactly sure what I'm looking at. It looks like a metal brake, but it is way more complicated than I've seen. It has these sort of weird, double roller hinges? The top jaw has a slide that you can move back and forth to adjust how much room the top jaw can slide up or down... and it also has this dial in the front. When you turn the dial, little metal tabs in the front move in or out. One of them (on right) has graduated markings on it. When I removed the bottom blade, the tabs that move in and out are connected to a row of teeth. When the tabs are fully in, the teeth go to a slotted section on the back. The bottom blade totally covers the teeth when installed, and seems unaffected by their movement.
What am I looking at?

Thanks!

That is called a bar folder.the teeth? don't know, my pexto doesn't have them.

Thanks! I'm unfamiliar with this tool. I looked up some uses on youtube and I'm still a little stumped as to if I'll ever have something to do with it!

it's for bending flanges, some presets for certain angles, made for quick repeatable bending. Not many were made to do thicker sheets 22 ga is the limit on mine.
