Get him a Spyderco Military. Solid knives and not too pricey
If he were younger, I would have suggested something smaller because it is somewhat big for a folder, but for an adult it is fine.

ETA: From what I have found, you are either a Benchmade fanboy, or you like Spyderco knives. I have had many knives, including 2 Benchmade and 4 Spyderco knives. Spyderco has better edges, the hole for opening is much better than the studs, and I intensely like the G10 handle on my Military. You can also move the clip around to any position your little heart desires.
