The Civilian seems to be one of, if not the, most expensive of the Spyderco models. Why is this? I didn't think it could be the steel, other Spyderco models with GIN-1 like the Baby Goddard and the Solo are rather inexpensive. I've only handled the knife once and I don't pretend to know if it's worth the money or not, but I was just wondering what accounts for it's cost?
