I forget what the actual name is, but it can latch onto a metal strip and pull it tight around some digs to keep boxes and canisters in place, or to hold a strong back repair plate on a damaged pipe
I mean individually humans are pretty stupid. each one of us only knows so much information. But collectively we know a fuckin ton of shit.
I love coming on here and seeing weird tools I haven't ever seen or forgot existed. So many of us interact with something all day that many others wouldn't have any clue what it's called. We just don't notice because we are around that item and people who know what it's called.
