These heavy-duty pliers measure 6.5 inches long with a 1.5mm wide jaw at the tip. They can handle making loops in 12 to 14 gauge wire, but will also work beautifully when using finer wire, such as 26 gauge. The long padded handles are comfortable to hold and easy on the hands, providing extra leverage and control. Priced in the mid-range, you will find the quality top notch. This will be one of your very favorite pairs of pliers!
