I find I use my multi-tool almost exclusively in urban environments. My SAK gets some use too, but I almost never need a fixed blade for anything other than cooking or playing. Screw drivers, pliers, awl, file and blades all come in handy for me. Many an adventure has been put back on track thanks to those babies! In fact, at one point, I was tempted to carry two, after several mechanical failures on bicycle trips around the city.

To Jeanette Isabelle's point, I also have a small pair of EMT shears in my urban edc. I added them when I flew to Saskatchewan in the summer and had to leave my Leatherman at home. I took them out a while ago because they seemed redundant, but put them back in a couple weeks ago after my daughter took an ugly tumble of the playground slide stairs while we were on a family road trip. My Wave scissors just didn't cut it.
