How about a Spyderco Persistance? They are reasonably priced, well made and actually great steel. Very convenient design with some safety built in. Supervise use and it should be a decent choice for a young man.

I usually carry one or a Tenacious (slightly longer blade). I have been surprised with the quality and like the Tenacious more than my expensive Paramilitary model.

I remember my first Cub Scout knife, it was a Boy Scout pocket knife. I was sure proud of that one!
