For me, scissors are a redundancy. I keep the blade sharp enough to cut anything that I would need scissors for. However, I can see their usefulness
However, I too have been underwhelmed by the pliers based micro-tools. As it would happen, my wife seems to have solved the issue for me

She picked me up a SOG Crossgrip for Christmas. No bigger than a LM Micra, it has plier jaws with additional wire cutters that use the SOG compound leverage. It'll nip through a coat hanger with no problem and gives enough purchase to turn most small nuts. It also sports a blade (chisel ground as it may be:barf

, tweezers, flat driver, funky philip driver, small driver with bottle opener, file with nail cleaner, and a lanyard hoop.
Like all SOG multies, the internal components are pretty rough around the edges, with the main tool body being well done and highly polished. They are also easily replaced with spares that can be gotten cheaply from SOG. IMHO, a tool of this size (Micra, Squirt, etc) is too much for my keychain. I keep mine either in my fifth pocket of my jeans or in my cargo vest. Once I got a good edge on the tool, I have been most happy with it and have used it several times this week.
Here's the kicker. It has recently been discontinued by SOG
