I figured it was about time that I took my pipe apart and give it a cleaning, since I couldn't ever seem to get a pipe cleaner down to the bowl. When I took the stem off I noticed there was a little metal piece at the end of it. My other pipe that I have doesn't have this, just a big hole. Can anyone tell me what it is and why only one of my pipes would have it?
Hopefully I've attached the picture correctly to show you what I mean.
