P38 can opener

Now here is something you must have in your B.O.B. I would even think about putting it in your mess kit. Maybe even on a keyring that has other little items on it. You can pick these up for under $1.00 at any army surplus store. You can also go here: http://www.armysurplusworld.com/product.asp?ProductID=16759 Pick one up today you will be glad you did.
