Spare ceramic ball bearing washers for Honey Badger pocket knives, sold as a pair. The bearings sit on either side of the blade at the pivot and are what give Honey Badger folders their smooth, quick opening action. According to Honey Badger, these ceramic bearings are compatible with all Honey Badger pocket knives; standard Honey Badger knives ship with steel bearings unless stated otherwise, so this set is a popular upgrade as well as a replacement part. Ceramic balls do not rust and run smoothly with little lubrication. To fit them, the pivot is opened with a Torx driver, the old washers are swapped out and the pivot is re-tightened so the blade runs freely without side play. A drop of knife oil after fitting helps keep the action smooth. Each ring holds a set of balls in a cage, and the pair covers both sides of the blade.
