I've got a Swisstool Spirit and am happy with it. It was larger than I expected (Amazon's measurements were off by an inch) so I was disappointed initially. However, I decided that anything smaller wouldn't have been useful as pliers. They're well made and I recommend them, but the pliers will only perform the same sort of tasks as a pair of standard long-nose pliers -- if for no other reason than 4-1/4 inch handles only provide so much leverage. The Swisstool Spirit has a lot of tools, they lock, and the price is good for a multitool with a lifetime warranty.

I paid $58.20 for my Victorinox Swiss Army Swisstool Spirit Multi-tool Plus Free Pocket Knife when they were on sale last November; they're currently $71, but you may find a better price if you shop around and/or can wait for another sale. I carry mine in my right front pocket rather than in the belt case it comes with; it's a little larger than I wanted for pocket carry, bit not hugely so. I also like the little Rally knife that comes in that combo; it's on my keyring.
