Spyderco makes great knives. I own several. The Endura is a good one. You might also want to look at the Delica and the Native. Though I own both the serrated and plain versions of many, I find the plain edge more versatile. All really, really good, and not too expensive. Great bang/buck.

For everyday multipurpose use in the urban environment it's awfully hard to beat the old Swiss Army Knife. I own a ton of these, and always carry at least two in addition to my locking folder.

OK. Maybe that's overkill, but I always have a teeny weeny one on my keychain (Classic SD or Rambler), plus a medium sized (84 or 91mm) one, like a Small Tinker, Recruit, Alox Bantam, Cadet, Soldier, etc. Don't poo poo them. I keep mine sharp enough to shave with. They'll make short work of seat belts. Plus they have screwdrivers, tweezers, toothpicks, scissors, and the all-important bottle opener. And they're less scary to the PHRASECENSOREDPOSTERSHOULDKNOWBETTER.. They're also very small, light, dirt cheap and last forever. For many, many years all I carried knife-wise was a Small Tinker, and it never let me down.
