As much as I'm not a big Spyderco fan I do have to say for cutting boxes they are outstanding. With a Police model that I had for awhile I didn't just open a box, I would cut the ends completely off (until I accidentally cut the end of a box off that was in the box that I was opening). And if you really look at a bunch of websites you can find some pretty great deals on Spydies, especially the newer ones with VG10 steel. The VG10 really holds an edge. This is really a pretty good recommendation coming from someone who is a Microtech, Dalton and Sebenza junkie (and a recent DDR convert).
I've also owned the Gerber Applegate Fairbairn series of folders. The combat although a good sturdy knife is probably too large for what you're looking for and the Covert I just wasn't too impressed with. For the money ($70-$80) you can get better.
