Definitely nothing wrong with the Blur you've been eyeballing, but here are a few other suggestions...
ESEE Avispa(~$30) nice frame lock design is thin in the pocket so it carries well yet packs a fairly substantial blade. Been carrying mine for a couple weeks now and really like it. I was going to recommend Ontario RAT-1(designed by the same guys as the Avispa), but it's a liner lock.
BM Griptilian(~$100 new) can be found of the BF exchange in your price range. Super solid lock, good blade steels, comfortable to use and carry, just a tough design overall. Can't go wrong with a Grip.
Spyderco Military/Para-Military - also can be found on the exchange for a little bit more than what you've got budgeted, but well worth it. I didn't care for the looks of Spyderco knives either, but once I handled them my mind changed quickly. They carry very well in pocket, handles are comfortable to use, action is smooth, lock is super solid even on the Military's liner lock, and Spyderco's S30v is great IMO. Give em a shot!
+1 for the Cold Steel American Lawman recommended above! Nice tough knives!
For your price range and uses, I'd probably recommend the Avispa and then order yourself a Mora for another ~$15 or so. You'll have both bases covered and still have money left over!
