In public I carry a Spyderco Gunting in a custom belt sheath that I never use for utility purposes, and I also usually carry a small folding knife for utility work - either an SAK or a Spyderco Kopa. I never forget my Gunting, but occasionally I forget to carry the small folder, which is OK because I have a backup small folder in every briefcase, messenger bag and backpack that I use, plus a couple in my desk at work.
