Aside from numerous blunt weapons in Battlefield Hardline, the game also features ten different knives. Unlike past installments, they are not the default melee weapon and must be unlocked via Battlepacks in order to use. Each knife is also counted as a separate weapon from one another. The weapons themselves functions similar to its Battlefield 3 counterpart, allowing players to perform slash attacks on enemies for 75% damage per hit, as well as Knife Takedowns.
Golden variants of blades are also available though the completion of Syndicate assignments. While functioning identical to their normal counterparts, golden blade kills are counted separately from their normal counterparts and do not require their ownership to obtain nor are they faction specific.
