I must have been about nine years old when I was given my first knife. It was one of those Swiss army types with one blade and a variety of other useful accessories such as a bottle opener, corkscrew, scissors, tweezers, and a file. Some even sported a fold out spoon and fork! The current most expensive model has 73 functions and goes for nearly $400. Check it out on Google, it is called the Swiss Champ XXL. Probably not a good idea to walk around with this knife in your front pocket, so a leather belt pouch is available.
