Personally I never had many good tools to work on mechanic "projects" and when I started to get a handful of decent ones I still couldn't get my head around this frustrating situation of a rounded nut or bolt, whether on bicycles, cars, vans or whatever that's held with nuts & bolts.
This is like an epiphany to me! That tool's inventor I want to hug!

Thanks a bunch for that one Scotty Kilmer. Here is Scotty's video channel. Some people comment that they can't take the way he speaks. I only see a lot of life, positivity and no nonsense in his tone (which I like it if you asked me but you didn't) and it also comes from the video editing that is fast and furious. He also does Live talk as mechanic online.
As a film-making enthusiast I ought to ask him who is the videographer behind the youtube content and how they work together on the script!
