Like others have said, it is a Cent 3 or 4. It looks like a 4 based on how the blade curves toward the handle but it may be the 3 since it is a drop point.
The good news is, that is one of the best Spydercos being made today. I carry and use my Cent 4 more than any other Spyderco. It has replaced all my Delicas and I think it is a more refined knife than the Delica. It is very light and slim yet is much stronger than it feels. I took mine hiking a few weeks ago and I put it to rough use. I was surprised that it stood up so well.
I bought it because it is one of my cheaper Spydercos and I didn't want to risk losing my Military since I was going to be climbing rocks and swimming. I figuired it was better to lose a $45 knife than a CF Mili that would be hard to replace. I end up using it more and more all the time because it is such a great design.
JDSpydo, you have to check one of these out. I think you will be impressed. I think you would perfer the Cent 4 since it is a Wharncliff blade and you like the hawkbills so much. I give it my seal of approval.:thumbup:
