Besides keys or electronic key fobs? On the chain with my housekeys and keyless car fob, I have one of [these](https://www.amazon.com/gp/product/B00UZHT432/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1). It is a handy gadget for opening clamshell packages, cutting cardboard, and other stuff that takes the edge off a pocketknife. I reach for it many times daily. On the keychain with my shed keys, I have one of [these](https://www.amazon.com/gp/product/B001UAMCL4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1). It’s a cute little thing. The knife blade needed to be sharpened right out of the box, but that didn’t take long. It sees use mainly as a bottle opener. The only thing really wrong with it is the shitty wire carabiner clip. Forget about it. Use the philips head screw as your point of attachment to keychains. I see people with all manner of shit dangling from their keys. What do you have? ---

I used to have one of the US Army issued P38 can openers from the old style c-rats. It was completely useless. In my life, I maybe opened half a dozen cans with it. The hazards of carrying a small, kind of sharpish, open blade around in my pocket eventually dawned on me. So I upgraded to a [F.R.E.D.](https://en.wikipedia.org/wiki/Field_Ration_Eating_Device) It’s even larger, just as hazardous and more pointless but it’s odd enough so that some people ask me about it when they see it. ---

I have a knife that looks like a key. Kids gave it to me. I have 1/4t. aluminium measuring spoon I found on the ground. That’s all. A former keyring I had a petrified alligator foot. Bought at a joint in New Orleans. I sat it down on low table one time and my foster dog ate it. ---

The only thing that isn’t a key is a Jetbeam Mini-1 Cu flashlight. Looks like they’re discontinued but [here’s an old listing](https://www.knifecenter.com/item/JTMINI1CU/jetbeam-mini-1cu-rechargeable-copper-led-flashlight-130-max-lumens). It’s got a microUSB port to recharge the battery and is overall a little under 1.75 inches long, very cool little light and has taken on a really nice patina. It’s connected to the main split ring with an old lanyard from a long lost [Maglight Solitaire](https://www.amazon.com/Maglite-Solitaire-1-Cell-Flashlight-Silver/dp/B009SKX89I). ---

A [trigger snap.](https://www.wholesalemarine.com/sea-dog-bronze-trigger-snap/) Back when I was taking karate classes, I didn’t want to leave my purse in the locker room, so I’d leave it by the training room where I could see it. I’d attach my keys to the purse strap so I couldn’t leave without my purse. ---

A small quantity of (radioactive) tritium in a phosphor-coated capsule. It glows faintly with no need to recharge. The tritium has a half-life of around 11 years, and I’ve had it about that long, so it’s about half as bright as it once was. The glow isn’t visible in normal indoor light, let alone sunlight, but I can always spot my keys in the dark, even through the pockets of my jeans. ---

A dogtag with my name and phone number on it. We visited a little community museum a year or so ago and they had a working WWII vintage dogtag engraving machine. For $5 they’d engrave a dogtag with the wording of your choice. I thought that was cool so got an ID for my keys. What I really wanted was the machine. ---
