Glock_Racer -- Bayou LaFourche, one of hte best web knife vendors in my estimation, has the plain-edged Merlin for $45. I'll attach their picture of it.
Want to second the recommendation about the fragility of the point on the Civilian. Not a hard use knife at all, according to much I've read.
I tend to think that the more plain hawkbill of the Harpy and Merlin have considerably stronger blades than the Civilian and Matriarch. Also, should you ever be frisked by an LEO, I think explaining the utility uses of hte knife would prove extremely difficult. There are many other knives out there -- including several Spydercos -- that are, IMHO, more effective self-defense knives than the hawkbills. If, of course, you're well trained in the Philippine martial arts, that would be the opposite for you. Yet, those other knives don't scream WEAPON at you when you glance their way. Something to think about.
Good luck with your choice.
