Thanks for all of the advice so far!! I was not expecting so many responses already - you folks are a wealth of knowledge!
I guess my price range would ideally be anything under $75, although I would be willing to pay up to $100. The roles for the knife would be simple EDC tasks (cutting cardboard, opening mail, cutting up food, whittling, etc.) but since I would have it on me all of the time, I would also want it to be able to cut a seatbelt quickly in the event of an auto accident or similar emergency. A glass breaker might be nice, but I know that really narrows down the selection (Benchmade Triage 915 comes to mind). And last of all, and probably the least likely role - emergency self defense. I have my CCW permit, but there are some places that you can legally carry a knife where you can't legally carry a gun. I would prefer something that doesn't look too "tactical" as I live in a state that has no formal blade length requirement, per se, but the law does basically state that you cannot carry the blade with primary intent to use as a weapon. Also, I feel like assisted opening might not be a good idea due to the nature of laws in my state (while assisted opening is definitely not an auto, folks who don't really know knives might assume it's the same thing.)
A steel that holds it's edge well would be ideal - I don't know too much about the VG-10 that the standard Delica comes with. Also, I think I would like to have a lock on the knife - I would feel safer using it in the field for the roles I described than a slipjoint. I almost purchased a Zero Tolerance 0350 on Amazon for $90 the other day, but I am personally not a fan of liner locks (or frame locks). My limited research has shown that they can fail more than a lockback (Delica style) or a ball-bearing lock like the Axis or Arc lock (BM Griptilian or Spyderco Manix 2 style).
