I would encourage you to consider adding just a little to get a good quality knife. My personal two all time favorites that I've used more than all of my other knives combined are:
Benchmade Axis Lock Griptillian: Benchmade Griptilian reviews, styles, and other information about the Griptilian style EDC knife.
And in fixed blade the Essee Izula II: ESEE Knives
The grip on the Izula II even fit's larger hands perfectly. Either of these knives will last him a lifetime; their quality and design are about perfect. The Benchmade is in my pocket every day but when I head to the woods or water, the Izula comes with me.
