Those four are a cinch - so long as I have my purse. I always have at least two sets of flashlight-whistle-knife because those are on my house key neck lanyard as well as on my car key ring. There's always a bandanna in my purse.

My purse has gone to all meetings since the anthrax attacks which occurred a few weeks after 9/11.

I also have a firesteel-striker and tiny prybar on my car key ring.
