Not stupid, its not a tool you'd ever come across unless you're playing with lenses.
Yes, a little pin spanner.
Here's a picture of a cheap one from eBay;
Lots of lenses have the front element (and often more inside) held in with a threaded ring with two slots of holes to engage with a tool. It's usually a big thread (67mm on the lens I'm trying to fix) so it doesn't take a lot of loctite or corrosion to stick it really solidly in place.
