You know those metal benches with metal arches for "arm rests" a lot of cities installed about a decade ago?
A lot of them use standard size bolts and Allen keys. No security, or maybe torx if anything.
Also an adjustable crescent wrench and multi-size Allen wrench tool fit nicely inside a pocket.
A cordless impact driver and associated bits fit in a small backpack as well.
What do those tidbits of info have in common?
Well that's up to the reader.
TO BE CLEAR, in case anyone doesn't understand, I am advocating for people to go out and disassemble anti-homeless architecture as a fuck you to the people who put it there. Being homeless is never a choice (not counting extreme outliers). Life is already shitting on them, denying them even a bench to sleep on for the night is just evil.
I've gone a step up, and am inhaling chunks of metal.
(I operate a saw cutting aluminum and have decided to wear a face mask but should probably wear a respirator instead)
