This heavy duty cutter is extremely strong. Use this tool for heavy gauge wires, bulk chains, and more. This cutter combines comfortable grip coating and extra fine tips to ensure precision cuts every time. As a safety precaution, the pliers have a locking mechanism to keep them closed while not in use. This apparatus has a good amount of counter pressure to ensure that they will not come undone on their own. As with all cutters, use them with caution and always point them away from yourself.
