Gee, not much I guess! I carry a SAK Rambler tiny knife, a cell phone, Zippo, Omega Seamaster. wallet with money and various cards, keys, a P-38, a comb, a Fisher Space Pen, Astronaut model, and a chapstick. Clothes suitable for the weather. It is a big city and I have only been stuck on the road once and wished for some cold water! I now carry water in the car during the commutes. That is it folks.
