In my quest for the ultimate EDC knife I have bought (and sold) several knives. I'm a scientist by trade and can't whip out huge knives, it will easily upset my gentle co-workers. So I purchased the Spyderco Techno, I love it. The overall build and the stonewash? finish on the blade is awesome (see picture)
