For a small/cheap/light pocket knife that's good for slacks and everyday wear, I like Kershaw's 1700 LFK. Can be had at about $25 at most sporting good stores, ebay, and elsewhere online.
Blade is 2 1/8 in. (and very sharp out of the box) and weighs 4.2 oz. The AUS6A steel isn't the greatest, but it's sufficient for light work.
