This is one of those "I'm bored" threads. Anyway, I have three keys (F150, Aerostar, and House) on one of those spring steel rings (I believe they are called Split Rings). Since I carry them in my pocket almost all the time, I hate a bulky key ring. I suspect most men will have minimal key rings with few keys for personal use, while some may have big rings of keys for work (especially if you are a maintenance man at a building or facility), which is more like carrying tools.
