Designed To Be The Best. Saunders invented the Nok Set and nocking pliers in 1964. Since then we have made several styles but none match the performance and comfort of our new pliers. Air cushioned grips conform to your hand. The self opening jaws are non-marring and just the right width to see alignment during closing. A new tip opens Nok Set in one easy squeeze. Each pliers comes with 3 Nok Sets®.
