Errr.... no! I don't quite understand what you mean, but boy am I going to investigate when I get home today. Thanks for correcting me!
It's a bit more than I described. I usually do this using a very tight-fitting converter I happen to have, but the best way I can think of to do it without such a handy tool is fine tweezers, with perhaps some electrical tape around the ends for a delicate grip.
If you gently grip the piercing nubbin, you can unscrew from it (normal left-to-loosen thread). Best to soak it first, in case of dried ink, preferably in some ammonia solution. Oh, and a tiny bit of heat - just a few degrees perhaps (not more than 30C) - can't go amiss.
