For me, it's definately easy access.

I use a small coffee can with lid (unsealed) in which I carry survival and utility items. It's my utility can, not a PSK per se.

I open it up and play with it from time to time to make sure that I always know what I have on hand.

Contents of the can is mostly redundancy items (firestarting material, knife, small light) since I usually also take other, full-size items with me such as a larger knife, a large Bic lighter, and so on and so forth.

The can does contain stuff that is not redundant, such as a Heatsheet survival blanket, large orange trash bag, wire, cord, tape, safety pins, a candle, stuff like that.
