Good beginner knife for a teen
I chose the Hiker Swiss Army knife for a thirteen year old and he really liked the features. There are large and small blades, large and small screwdrivers, can and bottle openers, wood saw, tweezer, toothpick and key ring. The size is about 3 1/2 and fits comfortably in the hand. The components are a bit tight when you're first pulling them out but will ease up with repetitive use. I would recommend growing a nail on your fingertip so you can catch the groove and pull out the component more easily. I also got the knife engraved with first and last names plus middle initial and the engraving came out clearly and not too big or small.
