From Spyderco's website:
"In the 1990s Spyderco was
approached by a specialized branch of U.S. law enforcement about making a
knife for their undercover agents. These plain-clothes LEOs found
themselves in situations where they often could not carry a firearm but
carrying a knife was not a problem. Most had no formal training in
self-defense tactics or MBC but as a last resort could use a blade to
protect or extricate themselves from a life-threatening situation. This
was how the Civilian model came to be.
The
Civilian has a patented reverse "S" blade that's intended to be used
like an oversized claw. The tip is ground to an ultra-thin profile.
Deeply curved and full at the belly, the VG-10 ground blade excels in
slicing and is available fully SpyderEdged. Because of its distinctly
specialized features it is not intended or designed for general utility
or everyday use. Curved in all the right places for ergonomic use and
retention of the knife, the handle is black G-10. Mounted for tip-down
carry with a custom curved black clip, the knife rides deeply and
unobtrusively in a pocket. One of the most specialized CLIPITS in the
Spyderco line-up, the Civilian is available in limited quantities."
I've had this mine since about '95. They've changed the handle color since then as well as the clip design. Great knife and sharp as hell. I never carry this one though, it's just collecting dust in the knife safe.
