Designed To Be The Best. Saunders invented the Nok Set and archery nocking pliers in 1964. Since then we have made several styles but none match the performance and comfort of our new nock set pliers. Air cushioned grips conform to your hand. The nok plier’s 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 plier comes with 8 Saunders Nok Sets®. (2 of each size).
