I've no idea what it's for. I feel it might be for opening can lids like on tins of golden syrup but that's just a guess.

A couple people already said it, but here’s a brief demonstration.
I'm going to assume this video covers my assumption lol
As others have said, it's to lever open the pull tabs on a soda or beer can, without having to use your fingernails. Flip the tool over and slide the flat blade under the pull tab and lever it open.
It might be an upward thrusting device for funnelling stubborn lids during the initial or halfway point of dislodging a stubborn bottle cap.
It's a secret device 007 uses according to his license. Otherwise it's a beer bottle opener and key chain.
You’ve guessed it really well 🙂
That flat, slightly hooked bit is designed to help lift ring‑pull can lids. You slide the lip under the ring, then use the handle for leverage so you don’t strain your fingers.
I’ve had a similar keyring on my keys for years; it opens bottles, but it’s also great for stubborn soda or beer cans on picnics 🍺✨

Can opener. You slip that under the pop top tab and push down on the part of the opener that's hanging over the edge of the can and that lifts the tab up.
That flat bit is for opening the Zip top on a soda (or similar) can.
You stick it into the hole and then lever it up.
I'm not sure, I've never seen it before. But I think you might be right, probably some kind of bottle opener.
Looks like you'd use it to open flat-topped cans. A Can opener...
Oops! Read that wrong. I thought it said what is a flat tit for. 🤣😂😅
That's to get caught when pulling the thing out of your pocket to piss you off and buy another less annoying keyring
Looks by the wedge shape and direction on the end, it pulls up tabs on cans.
I had an idea, b ut looking closer, I've got no idea
That piece is for your thumb, so you can use it as leverage to use the pressure to open the bottles
It’s for coke can sometimes tab can be hard to pull.
Isn't it for opening ring pulls on cans.
It is for tin lids.
it looks like a key...
Yes, or maybe it us a screwdriver
A safe cutter for tape on boxes/packages
Good idea. Ring pulls are the devil's work!
Soda cans, so you don't break a nail...
Opening flip-top cans
It so it doesn’t break I guess.
thats another opener probably
No idea
Lunchboxes?
