Atwood Prybaby
A prybaby can be found more and more in EDC kits. Small and practical the prybaby is a keychain item that can be used for several different things.
It's primary use as its name indicates is to pry things, constructed in s30v steel the small prybaby can lift a lot of weight before suffering any deformation. I have used to remove a door from its frame and worked without suffering damage.
Besides prying things the tool comes with a bottle opener, and a scredriver tip on the other end. The tip of the tool can be used to remove nails, scrap paint, open boxes etc.
Making it short the number of real uses for your prybaby depends on you, the longer you have it the more you discover how useful it can be. You can get it for $35 directly from Peter Atwood's website.
