Wire cutters are an essential tool for anyone working with electronic equipment. Whether you're running wires for a home theater or repairing a broken device, these tools make the job easier. There are many cheap wire cutters which will simply cut a wire in two. But sometimes you need to cut away the rubber from a wire but keep the metal conductor inside intact. In this situation, you need a precision instrument. The best wire cutters have precisely measured grooves for just this purpose. Depending on the size, some wires can be difficult to cut, so make sure you buy a pair that is up to the job.
