DEV, for "most defensive applications" you might want a more conventional blade. There was a very good thread on Hawkbill Blades on the Mad Dog Knives Forum over a month ago. The URL is: www.knifeforums.com/cgi/Forum12/HTML/000437.html (hope the address works, sorry I couldn't get it as an active one here). I especially enjoyed Scott Evans' and Joe S's positive comments, but don't know how accurately they'll translate to just the Civilian.
If you insist on having a hawkbill folder, perhaps as a secondary or tertiary knife, I have good experiences with the Spyderco G10 Harpy as a weak-hand reverse-grip thing. Of course it is small compared to the Civilian, but it conceals and works very well.
My two cents.
