These exclusive Patent Pending pliers, invented by Wyatt White, are a must-have tool for making the initial tight band that hold wire designs together. These pliers create the perfect double right angle bend on 22 and 24 gauge Half-Round -and is perfectly sized for 22 and 24 gauge Square Wire banding. The double right angle bend in either Square Wire or Half Round Wire fits the corresponding Square Wire, making the first "binding" wrap very tight and secure. This bend reduces the time needed to create professional wire wrapping and stone setting. Each end of the T-shaped head fits a different gauge: Item #201A-290 is sized for 22 and 24 Gauge Square Wires. If you are looking to use a larger gauge wire try #201A-289, which is sized for 20 and 21 gauge Square Wires.
