I used to have a lot of stuff on my keyring but felt it was getting too big, so removed nonessentials. What's left: 1) a bunch of keys; 2) Spyderco Jester (Forest green plain edge) and matching Photon II with white led; 3) Photon II knock-off ($1.25 from KevinL on CPF) with red led for not messing up night vision; (sometimes, depending on my mood) Peak Led Solutions 1AAA LED light on Berkeley Point micro-clip.

I do carry some additional stuff in my belt pack, notably a cheap orienteering compass, SAK Explorer, tiny earpiece AM radio, and sometimes a PT Aurora headlamp.
