It is great that you want him to have a knife, but he needs to learn all the responsibilities of knife ownership, and needs supervision until he is 10 or 12 years old in my opinion.

Looking at the engraving, I didn't receive my 1st lockback until I was 12.. And 1st "big boy" pellet rifle at 10 (step up from the Red Rider) but between the ages of 12 and 14 I was given my own responsibility with everything hunting and outdoors related

including running around the woods with a WW2 era Navy Kabar and a Rambo "survival knife", pellet
pistols, unsupervised pellet hunting, skinning, and the privilege to
carry my own .22 or .410shotgun
while on hunting trips and handle the .30-06 instead of having the rifles handed to me by my Grandfather when he spotted a suitable target, like it was when I was 12. So those two years came with
a lot of responsibility..
Just some guidelines from how things went in my own life and I still have 4 limbs, 2 eyes, 10 fingers and 10 toes. So it worked out fine.
Having received my first knife as a Christmas stocking stuffer from my grandmother at six years old ,might I suggest a larger SAK model a tinker or camper ect. I feel having had my share of cuts and accidents with knives as a boy I think a non-locking knife is the best way to learn what knife safety really means .I don`t mean to offend others by telling you differently than they say but I have never had a locking knife fail and cut me because I always treat a folder as such ,a thing that is sharp and meant to fold . I am always aware of the chance my knife may close without warning and this is because the first 10 knives I had were slip joints .A nice little fixed blade can be good but it will not teach as well as a nice little multi blade slippie. A Leatherman would also teach him about a good tool and how pinch prone things can be.
Learn through pain.. I was gonna say something like that earlier but I didn't want to offend either. Those slipjoints closing on my fingers time after time was the only thing that taught me how to properly use them.
BUT as young boy, I doubt he'd stop using the 2 he already has; probably carry all 3 around with him. Uprade him
