A product sample of Channellock's 758 Flush Cutters showed up several months ago, and we've since had the chance to use it extensively. The Flush Cutter is designed to cut plastic and soft copper wire: 10-20 AWG copper wire, to be exact. The Flush Cutter isn't designed to cut steel wire. In fact, it says “not for steel” right on the tool.
We haven't had the occasion to cut copper wire with the Flush Cutters, but we've cut off tons of zip ties. The Flush Cutters work well, as they slice off the tag end of the zip tie and leave almost no protrusion behind. The remnant of the tag end is fairly smooth, almost as if it had been touched up with sandpaper.
The Flush Cutters are comfortable in your hand; the blue-coated handles feature a gentle taper and a length that provides authoritative leverage when it's time for cutting.
Why use a Flush Cutter and not just reach for the diagonal cutters you already have? Diagonal cutters do a good job of cutting harder materials such as steel, but they also leave behind a noticeable stub. What's more, the stub is often sharp enough to draw blood if you catch it the wrong way.
No off-roader should be without zip ties, and the Channellock 758 Flush Cutter is the best way to cut zip ties. It's the new must-have we never knew we needed.
One final note: Channellock tools are "fiercely" made in the USA. High-quality, American-made tools are always welcome in our toolbox.
