Hairpin
Scissors? No, there’s no hinge or blades. Chopsticks? Seems like you’d have to break the object to use them for eating. The OP had no idea what this thing could be, even after asking several family members. So, they took their curiosity to the internet, where helpful strangers provided answers.
It turns out that this thing is a hairpin, as in you poke the two prongs into your hair to keep your bun in place. These things are actually a lot more common than you might think. They even have them for sale on Amazon. But this is the first time we’ve seen a hairpin this clunky.
