It isn't a Leatherman or a Gerber, but I carry a Schrade Tough Tool. Perfect for computer work. Needle nose pliers with wire cutters and wire strippers on the screwdriver, a metal and wood file. The file really comes in handy. It has a big serrated blade and a smaller 50/50 blade. Four of the blades lock: Knife, Philips, and flat screwdriver, and the big serrated blade. Best but not least it can be opened one handed, butterfly style. I have used it for 6 years doing everything from home wire projects to getting into computers. It has never let me down.

All the blades on the Gerber lock. On the Leatherman, I have no idea if the blades lock. I have a Leatherman Side Clip, none of the blades on it lock. I also have the Spyderwrench, but haven’t used it yet.
