If you are at all concerned that people will see it as a weapon and not a tool, then something less 'tactical' looking may be a better choice in today's post 9-11, post VT environment. I used to have a serrated spyderco, but traded up to a ritter grip. This was primarily because the serrated blade looked too scary and pointy, and i was less likely to carry it if i thought people (PHRASECENSOREDPOSTERSHOULDKNOWBETTER.) would think i was some scary dude. Also, the ritter grip has better steel. This was still too big, so now i have a small fallkniven u-2 pen knife in the pocket, and the ritter grip goes in the 'kit' bag. I think the u-2 was like $50 and it's small but very sharp, perfect for apples, cutting open packages. Another good choice for urban carry is the locking swiss army knife, the trekker i think. Don't think they're much over $40, has lots of other tool blades and no one thinks of a SAK as a weapon.
