my kit,the overboard PFD "camping kit" is ment to be used in it's entirety. however i can see where most kits would be the sort of thing where you tell yourself-"if i only had---- i could get out of this" so you can pop open a container of some sort and save the day.for fire making i think the multi devices fall into --easy,hard,almost impossible categories.you don't want to waste a lifeboat flamer if a paper match would work.
