The ring is usually worn on the left hand, but recent graduates have switched to wearing it on the right (it’s rumored this is done to accommodate for wedding rings worn on the left hand). Additionally, the ring is to be worn so that the class crest is on the inside, closest to the heart.
The term ‘ringknocker’ developed from the rumor that some graduates would rap their ring on a hard surface to show their superiority. Some think the term came because graduates would tap their ring during a discussion, and all other cadets would then have to back up his/her point of view. (We should probably note here that we have talked to non military service academy veterans who have indicated they never witnessed any ring knocking and that they do not believe there is any basis to this “urban legend.”) ‘Ringknocker’ can sometimes have a bad connotation, but the tradition behind the military academy rings is still strong at the military service academy institutions.
