I love the features built into this tiny tool. There is a cross hatch jaw (grip), a wire puller notch, a non marring grip (if working on a high polish surface), a torque zone, a fastener grip area, and a cut zone.
These Long Nose Pliers feature a high leverage joint design that provides up to 35% greater cutting power (capacity of 11 AWG - FYI electricians). The pliers also feature laser-hardened blades that remain sharp for 50% longer, which is convenient. I find the textured rubber handles to have a great ergonomic design.

I think this tool is a MUST buy for professionals. The Z2 line of pliers is Crescent's top-of-the-line.
The textured rubber grip feels great vs. plastic, and the appearance is high-end (matte black on polished metal really pops).

The handles are NOT electrically insulated. Made in China. They come with a LIFETIME warranty. Tether ready, but I’m not sure I’ll ever use that.

Mine had a lot of oil on it, from the manufacturing process. That probably protected the tool, but the amount was a bit excessive.
