I love this stuff.
I've kinda taken to collecting the absurd little "EDC" gizmos that have popped up, to a large degree since we got a black man in the White House who was gonna take all our guns and make society collapse into a zombie apocalypse. I bought one of these direct from China for less than a buck shipped. Because, why not? Persuaded by the pictures showing the clip being used to drive fasteners, cut rope, peel an orange, shave a carrot, turn into an oil lamp, and even shoot rubber bands. The only thing it really does reasonably well is hold down a hank of hair, though.
However, these often keychain-sized quasi survivalist gadgets go back a pretty long time. I remember as a kid in the 70s occasionally seeing these fidgety gizmos ancestors in the backs of man/boy magazines and occasionally in the hands of an actual man/boy. I started collection about 15-20 years ago when I came across this odd credit card sized piece of stamped steel that has a bottle opener, can opener, knife edge, saw, screwdriver, nut driver cutouts, and a number-less measuring scale that corresponds to neither metric nor imperial units. Those things are still around, and have morphed numerous variants, along with the various silly thumb sized prybars, tools, and weapons, occasionally in exotic metals and finishes, at boutique prices. Dog love the free market!
