I've got a Case trapper with yellow handles, just like the one T LEE posted.
Last year I replaced (stuck it in the safe) it with a stag horn Case trapper with stainless blades, to keep it from rusting in my sweaty pockets.
It holds an edge way better than I thought it would.
And, YEP! big boys LOVE pocket knifes! I'm always looking for another.
Kinda goes with the gun loonieism.
