What is that?

Tönjes gave me this tiny ‘tool’ because he thought I had left it at his Cafe (MÖRDER). But this wasn’t the case. Then we started guessing what this little needle sort of paperclip tool was good for. Someone said you would need this to eject a sim from an iPhone … is Apple still making you use of the  paperclip emergency technique?!? It is definitely useful to hit reset buttons in little holes but a ball-pen is usually enough for that, no? What is it for? It is definitely sexy, high end crafted, sturdy premium steel. Do you know?
