Owning various multitools from Leatherman (love their Crunch), Victorinox (excellent small ratchet wrench set), Wenger and others, I have to say that the PowerAssist is the best of 'em all - with only one shortcoming...which we'll get to later.
The current crop of SOG geared pliers are excellent, with a precision needle point, hard wire cutter, crimpers and integral stripper. The handles are comfortable - even when squeezing hard (the swivel cover plate helps here), and all the locks work well. Having two main blades is a bonus too, though I'm still not certain if I like the assisted opening action on each - we'll see how good that is when they're "run-in" a little more.
Finally, back to the shortfalls - which could elevate this tool to iconic status if incorporated. SOG should consider 2 modifications to the PowerAssist, both of which are simple:
a) Replace the black plastic 'filler' block between the main blades with an aluminium alloy casting (7075-T6 would be ideal), of the same shape - but with a Hexagonal, 1/4" drive socket machined into the 'butt' end. Add an extender and one's own selection of 1/4" drive bits stored in a strip, then store it all in a modified belt pouch. The main blade(s) rotation stop pin, which passes through the current filler block may need altering to accomplish this - or even remain as a hex bit locking device - but the SOG design team should manage this easily.
b) The pouch. SOG's current nylon variety has an excellent, low-profile, locking belt clip - which should be standard across the industry. No changes there, then. The place where two simple additions would help is on each side of the pouch, where a pocket for a small flashlight (Maglite Solitaire or similar), on one side, plus the aforementioned Hex bit strip - or a few 2" long bits - should slide in to a similar pocket on the opposite side.
There you have it - and SOG's clever Customer Care colleagues have my address - so I won't object if you send me a sample (for testing), when the modifications are incorporated...
If you need an excellent Multi-tool that you'll pass on to your kids, the PowerAssist is it.
