8 Best Wire Cutters for Electrical and DIY Projects

December 14, 2022

Reliable wire cutters are one of the most convenient tools in your toolbox, allowing you to safely and easily cut wires with minimal effort. These compact hand tools use extremely sharp jaws combined with a high-leverage handle design to cut all types of wiring, as well as other thin metal items such as screws and nails. They are also available in a variety of sizes, with small heads to reach and manipulate tight electrical components, or larger options to provide maximum leverage to cut extra thick wire.


What to consider


Make sure your potential wire cutters can handle the type and size of wire you will be using. Fortunately, most options will clearly state the range of wire sizes they can cut. This is sometimes expressed in standard AWG (American Wire Gauge) sizes. If you are not sure what to cut, it may be a good idea to choose a lower AWG rating. Remember, the lower the AWG number, the thicker the wire.

You should also consider whether you will be working around any type of energized wiring. If so, be sure to use wire cutters with insulated handles to protect you from any accidental electrical shocks. These options can sometimes be more expensive than regular knives, but a few extra dollars are definitely worth the investment. The National Fire Protection Association requires the use of insulated tools when working at voltages higher than 50 volts.


How we choose


We've been using wire cutters for a variety of tasks over the years and have used that experience to put together this list of useful options. In addition, while we don't have a ton of hands-on electrical experience, we understand the importance of cutting and stripping wire, which is why we offer two options that can be done simultaneously. We also did our best to exclude any unknown brands or low-quality models, because we know the frustration that comes from spending unnecessary time and effort fighting inferior tools.
