My husband is always watching those survival programs on TV. When I saw this I thought it would be the perfect gift for him. He likes to camp,hunt and go hiking. This was perfect for him to put on his key chain. It comes with several tools that are great if needed to survive. Sharp Eye Knife, Several feet of Paracord, Carabiner, Tin Foil, Cotton Tinder, Magnesium Flint Rod, + Fishing tools (Sinkers & Swivels, Hooks, Floats, and Fishing Line). I did not undo mine since it can not be put back together but it does come with a card that list everything that is included. I suggest that you know how to use everything in the kit and what you can use it for before you are in a survival situation. Check lots of survival uses for tin foil: http://urbansurvivalsite.com/33-prepper-uses-for-aluminum-foil/ . I received this product free. All my reviews are based on my own experience and evaluation of the product so that others can benefit in finding quality products that meet their needs & expectations.
