For the outdoor guy, I'd suggest a Benchmade minigrip; any model: Doug's, Cabela's or one of the basic Benchmades. I've got one of Doug's and one Cabela's. You can bring any of those in for right around $100.
And pick up a KaBar Dozier folding hunter for yourself just because. You won't believe what great knife that is for about $25.
For the city guy, the Spyderco Kopa (any of the handle variations) is a great looking knife. I think New Graham Knives has the Cocobolo handled one for about $112. The Spyderco Spur plain edge is a nice looking knife for around $65. I don't know that either are particularly light, but they are compact, well-built useful knives.
Here's a link to New Grahm:

If you end up ordering from New Graham, you'll like 'em. Good folks.
