i gave my brother a small lockback folder two days after he turned 9...he was mature enough but i don't think he is that interested because he almost never uses it. he got a lockback becuase when i was teaching him to use a knife, he tried to cut with the wrong side of the blade and i worried about him closing a slipjoint on his hand.
he also lacks some fine motor control so its a little difficult for him to use knives precisely...that will come with practice though.
i would suggest a plastic handled mora...folding knives are tricky for small fingers, and i always get nervous with the closing action...it is so easy to let a finger hang in the closing zone a moment too long and then there can be trouble.
also get him a stone, as was said. let him practice on some cheap beater for a while, just like most people learning to sharpen. this will save his good knife for when he gets the hang of it and can put a sharp edge on...
