The anonymous chap behind Hand Tool Rescue restores old tools and gets them into the hands of people who can use them. I'll get to him in a minute. First I've got to show you this insane DIY automatic tree trimmer that he posted on his Instagram:

I wish the damn video wouldn't auto-repeat because I become easily mesmerized by such things. I think I let it loop four times before I snapped out of it.

It's not known who created the contraption, but if you're interested in seeing unusual and old-school tools--a hand-cranked grinder, a gas-powered circular saw, a hand-cranked bandsaw, etc.--go from broken to fixed, click on over to Hand Tool Rescue's YouTube channel. Warning, though: Rabbit hole ahead.
