I ASSUME EVERYONE HAS ONE ON THEIR KEYS....OR DID AT ONE TIME.....SO WHAT IS IT?
I USED TO HAVE A STEEL POLICE NIGHTSTICK...BUT SOMEONE BORROWED MY KEYS AND LOST IT...AND BEFORE THAT IT WAS A SMALL BASKETBALL.....I HAVE NO KEYCHAIN CURRENTLY.
Never had one until some 6 years ago I visited friends living 1000 miles away who I rarely see in person.
They have a daughter who was 6 years old back then, she had gotten as a present from her parents a box full of little plastic things one can line up like pearls on a string.
She made me such a string, real colorful, quite cute, maybe 10cm long, to put on the ring with my keys.
I've kept it on until I've visited them again last october, the daughter being 13 by now, a really rebellious teenager, but when she saw that I still had that string on my keyring she was moved to tears.
Unfortunately those plastic pearls were so much worn out that they broke to pieces last month and I had to throw them away, meaning I'm back to not having one now.
I used to have a "military nightstick", filled with lead and tucked under my thigh when I drove a cab during the graveyard shift in a rough military town. I'm really glad I was never forced to use it. I can't imagine how you would have something like that attached to a keychain. π€
