Groovy Looping Pliers from Wolf Tools form the same size loops over and over again. One jaw is round and tapered for forming loops while the other is flat and tapered and has 3 grooves. Place your wire into one of the grooves and then form it around the round jaw. Use the same groove again, and the next loop will be the same diameter as the previous one. Made of stainless steel with PVC grips, dual leaf springs, and box joint construction. Length 5 1/4" (135 mm). Made in Pakistan.
