I'd like to say I'm happy with how my Park Pro cable/housing cutters (http://www.rei.com/product/692846) work. Good, sharp cutters. I found myself needing to trim some older housing (ends were a little buggered) and these cutters could nip off a couple mm of housing without buggering up the ends. A finish nail was still useful to round out the hole, but the cutters did not mangle the wires that compose the shift housing.
This was my first chance to use the Pedros cable puller (http://www.rei.com/product/697496) my wife bought for my birthday, and I'm so happy to have one of these tools. It makes installing new cables and getting the tension right so much easier.
