As most have already mentioned, one can build a better kit! My wife in her best intentions bought me the knife whistle, light combo as a stocking stuffer.
I would not have wasted my money (would never tell her) It's neat concept and would be better than nothing but the functionality of any single component
is kinda lame! The whistle isn't loud (better than no whistle) the knife is sharp and does lock but doesn't look very strong (again better than nothing) and the flashlight would be better than matches but most likely is useless past 12 inches. All of these items are items I carry every day!!! So I'm guessing it will go into a kit somewhere!
