Hello,
I am a diehard Leatherman fan and have carried a PST since 1993. It has never let me down. When I damaged the small screwdriver by using it for something it was not intended to be used for, I sent it back to Leatherman and they not only fixed the screwdriver but also updated the tool to their current specs - all for free with no questions asked. Leatherman also hardens all of their tool blades to the proper Rc for the function they were intended to perform (awl/punch hardenend different than the knife blade, etc.). Others may also do this but I am not sure.
I have heard the complaint about the handles "digging into my hand" many times before. IMHO, most Leatherman tools are based on a pair of needlenose pliers, and I don't count the pair of "full sized pliers" embedded in the needlenose. This implicitly makes it a light duty tool - something ideal to pull out staples, do electrical wiring, etc. If you're squeezing so hard on a nut as to cause discomfort, it's probably time to put down the multitool and go find a Craftsman or Snap-On for the job. If you're in the middle of no-where with no other choice, you should be happy you have anything to work with at all and accept a little discomfort. Leatherman also has many more choices available today that cover everyone from the office clerk to the auto mechanic.
For a comfortable Leatherman, go with a Wave or a Crunch (I hear the new Leatherman Pulse [based on a PST II design] is also quite comfy), For a heavy duty workhorse, go with a Crunch.
Don't get me wrong, I have nothing against SOG multi's. I have handled them in the past and they are fine tools. By nature I am very loyal to my brands and if I had bought a SOG instead of a Leatherman I would probably be singing it's praises.
Later,
MBS
