Get him a DMT Diafold.
I bought my dad a spyderco sharp maker several years ago. When he uses it he holds the rod in his hand and free-hands it. Whatever stones he's using he gets his knives sharp but they look like someone has skipped them across a cement parking lot (scratches). I don't say anything because he's been sharpening knives since way before I was born. I wince when he shows me a case tested knife with fresh scratches on a beautiful old patina blade.
If you see each other frequently, you could get him another sod buster and tell him when one gets dull, put the other one in his pocket and give the dull one to you to sharpen...
