Using these Klein Tools ironworker's pliers is easy. First, identify the soft annealed rebar tie wire you need to work with. Then, place the wire between the knurled jaws. For twisting, hold the pliers firmly and rotate them. To cut, squeeze the handles together. The spring - loaded design will make it open automatically after each cut. When using, make sure your hands are dry for a better grip. Don't use these pliers on materials other than soft annealed rebar tie wire, as it may damage the cutting knives. After use, wipe the pliers with a clean cloth to remove any debris. Store them in a dry place to prevent rusting. If the pliers seem to be getting stiff, you can apply a little bit of lubricant to the joint.
