I EDC'd the Civi for a few years after I mostly got out of collecting (it's a struggle). I kept it mostly for its cultural significance as an iconic knife, but being one of the classic Spyderco designs means it's also just a good knife. Great ergonomics and the full SE Spyderedge cuts really well.
Be aware that if you use it for utility purposes the tip will probably break. The one I bought many moons ago was discounted because of a small amount of missing tip, apparently on a fresh model the tip is incredibly thin by design.
Also the blade is just over 4" long, one of the reasons I love it but also something to be aware of.
If you're accustomed to using a fragile blade then I say go ahead and use it as an EDC utility blade, the reverse "S" is a nice cross between a hawkbill and a blade with belly. If you love the Spyderedge then this is an amazing knife.
(My EDC use is basically the same as everyone else, tape, cardboard, paper envelopes. I'm using a Mule for vegetables at the moment though, don't expect the Civi to do much in the kitchen.)
