Summary: Excellent nail pullers!
Comment: I agree with other reviewers here. These end-cutters are particularily well suited to pulling/leveraging nails. They are not as well suited to end-nipping. There are slightly better manual end-cutters for nipping where the pivot is closer to the jaws and the handles flare more widely resulting in better mechanical advantage. There are also ones with double-pivots which generate even better mechanical advantage and work well, but they can be unwieldy.
These however are perfect for nail pulling in that the jaws open wider, the head curvature is just right for the cam-action of leveraging a nail out and the narrower handles enable easy one-hand operation. As a carpenter I use these every day to quickly remove large stubborn nails with minimal damage to the lumber. Paired with a small Japanese prybar (Dogyu or others) they also work quite well for more delicate trim work.
By far, the easiest, quickest and least damaging way to pull nails.

Summary: Fine for wires and small nails
Comment: I just bought a 10" version of the 8" model sold here on amazon. It's a fine nipper for what it's intended for ... which is cutting the ends of electrical wire, small snails, and small bolts.
HOWEVER, it had real problems with the task I purchased it for, which was cutting off the protruding ends of hardened steel screws ... I heaved and strained like a bodybuilder, while perched atop a ladder in my garage, and every time I finally managed to nip one, the screw let go with a loud report, and shot away like a bullet - necessitating my wearing ear and eye protection. After 20 such nips, my hands were killing me, and I hunted around unsuccessfully for a pair of narrow steel pipes to slip over the handles.
I'm surprised none of the major U.S. plier companies out there make a 14" version, for this sort of use ... and trying to use my tiny dremel stylus with a 1" cutter wheel is almost a joke, and causes showers of sparks.
I'm sure if I was cutting wire, I'd be happy as a clam with these babies, but for cutting hardened screws, forget it ... unless you're a body builder with hands of iron.

Summary: Great Product.
Comment: You can't go wrong with Channellock. I have been using these pliers for a couple of months now to pull and cut nails. They are comfortable to use and provide fantastic leverage when pulling nails. I highly recommend.

Summary: Favorite tool, almost
Comment: End cuting pliers are one of the most useful tools on the planet. Someone needs to give them a better name, something a little sexier. I use mine mostly for pulling nails - they're the only way to go.

Summary: The Persuader
Comment: This is an excellent tool.I have two sizes, but use the 8" most often. It works well to pull nails, cut wires, nibble metal, and bend, break, cut, or remove all manner of materials.
The nipper gets into tight spots to pull nails when a hammer or pry bar won't fit.
I used this tool last night. I was removing an old fireplace for a basement remodelling project. I used it to pull nails from the wooden framing. Then I cut the thick wire in the reinforced fabric ducting connected to the blower assemblies. I used it to cut the 12 gauge Romex to the blower (diag cutters or lineman's pliers may be the purist' choice-but I had this tool in hand...)Finally, I used it to bend sharp, nasty sheet metal edges into less dangerous shapes/positions when I was ready to carry the firebox outside.
I have also used it in the past to grab rounded screw heads and extract them.
Dependable tool. Frequently and successfully used. Highly recommended.
