SOG Powerlock
I've carried a Powerlock for the last 10 years, I carry it for work (I'm a locksmith), the best thing about the Powerlock is the gearing giving you 2X the amount of force you're applying to the pliers/cutters, this is particularly useful in my work as I use the cutters to trim piano wires and the length of the flat spindles on the back of rim cylinders, I also use the pilers to bend/shape the piano wires. The only downside to the Powerlock is the fact the cutters aren't replaceable like the Leatherman ones are, so to keep them sharp you have to use a small metal file every now and again. But the quality of manufacture more than makes up for this small pet peeve of mine.
