What is the source of these approximately 5-6 inch long, about 1/8 inch wide, very thin (16th of an inch, perhaps) strips of metal commonly found in industrial areas (but not always). My suspicion is they are used in overhead power lines as some sort of strap? They are found on the ground and I have seen them in more than one city in the US.
Def. street sweeper bristles. Made from spring steel, these are used, among other things, to make decent lockpicks. Grind your own custom shapes and clamp on a handle.
Could they really be from street sweeper brushes??? Think about the dimensions in the OP. I don’t discount this idea, just find it a bit implausible (they really are small).
However, and this just occured to me after looking at toadspittle’s pics, could it be that street sweeper brushes are made of different sized metal strips? Never really thought of that. It is difficult to gauge size from the pics. They appear as the thin strips in pic numbers five and seven - then again I can’t tell the size from the pic, and my dimensions in the OP are fairly accurate.
But I do now consider street sweepers the likely source.
I started out with Isosleepy/Philster’s ideas, but found the strips far from industrial areas, and in higher numbers than one would suspect (so it was unlikely someone had carried them to these places). That lead me to think of the overhead power lines idea.
Heh, even before I read this I was going to post about the time I locked my keys in the car at the beach. I found two of these within a few minutes and was in my car a few minutes later! At least litter can be useful sometimes.
voltaire, I had a similar experience. I forgot the key to my car’s Club. I knew it had a crappy, crappy disk-tumbler lock, so I went out looking along the curb for a sweeper bristle. I found one in short order and five minutes later the Club was off and I was on the road!
Don’t tell Stephen King you have these. Don’t look around. They’ll know. Gather enough to stick them into a hedgeapple to make a spherical spiny thing, a little more than twice the length of your metal strips. Set it in the middle of your living room. Brace yourself. Oh, and take some ID. Got a Swiss Army knife? Take it. They like those. Rubik’s cube? Leave it at home.
