WTF lol I wasn't expecting this at all.
Surprised you never heard of them. These things have been the stuff of legend since the late 60s. https://en.wikipedia.org/wiki/Hitachi_Magic_Wand
Now that I'm 20 minutes in, good video. I like that air gouger and how he is able to knead the metal back into shape with the hydraulic press. Not his first rodeo :)
Yeah, that's quite satisfying. (the kneading) :D
Some of it looks a little sketch, like those blocks he's using might jump into his face. Especially the setup when he did the first pass of straightening the tool box.
I guess he's got enough experience to know how far to go and not a bit farther.
