I've never carried a large blade in NYC. For many years it was a Buck folder in its case. Now what I carry depends upon where I'm going and how I get there. Usually it is my Terzuola folder clipped sidedraw to the waistband of my pants. If it's more dress up a Spyderco Delicia. When my arm was in a sling after surgery I did carry a Gossman PSK in the sling when traveling on the subway to physical therapy.
