It does help to know the magic words when looking for stuff.
I use them for cleaning glue out of syringe needles. Do take the time to swipe the tips over some sandpaper, they are quiet sharp.
I prefer to use a torch to burn the plastic out of clogged nozzles, far less hassle. I don't print "exotic" stuff like carbon fibre so I don't have any ruby ones. I think they might be a bit of overkill for solder paste, the plain steel ones would be hard enough.
As the other poster said, plenty on AliExpress if you don't mind the wait.

Ah, they're sold as 'printer cleaning needles' on Amazon uk, in handy kits of
different sizes.
(I have also bought a bunch of 3d printer nozzles, including the jewel tipped and
0.1mm versions, to see if they'll dispense solder paste, but they're still on the
'to do' pile. )
