The Chef's Knife, also known as Tonberry's Knife, Kitchen Knife, Knife(ほうちょう, Hōchō?), or Cleaver, is a weapon of the Tonberry and a recurring ability in the Final Fantasy series. In most cases, Chef's Knife is a deadly non-elemental attack.
The Knife, originally known as the Cleaver, is Tonberry's attack. It can only use the ability once it has moved close enough to the player. Knife attacks several times, ignores Defense and inflicts Sap.
The enemy ability and the summon work the same. The Tonberries, most commonly fought in Centra Ruins, use the attack. Tonberries will walk forward on most turns, using Everyone's Grudge as a Counter-attack. Once it has come close enough, it can use its Chef's Knife attack to deal large, non-elemental damage.
Once the Tonberry King is defeated, the player will obtain the Tonberry summon. Its attack is the Chef's Knife and it functions just as the infamous Tonberry attack does. The damage can be increased by Boost and leveling up Tonberry's stats. The attack is also accompanied by a "Doink" sound for comedic purposes.
The Chef's Knife can be stolen and dropped from the Tonberry enemy and modified from their cards. Chef's Knives will increase a character's compatibility with the summon by three and can also be made into Death spells and AP Ammo.
While Tonberry beastmen have a devastating short-ranged stabbing attack, called Throat Stab (急所突き, Kyuusho Tsuki?, lit. vitals stab), that reduces a player's health to 5% and resets enmity, it is (unusually) not an example of the Chef's Knife. However, there are several different items that are some form of Chef's Knife.
The quest "You Call That a Knife?", involves fetching a chef's knife for a tonberry who has lost his. The player must obtain a Tonberry Board (a chef's cutting board) and deliver it to the tonberry Chef Nonberry, gaining the key item "Nonberry's Knife" in exchange.
The Tonberry appears when the player goes to kill the UndyingZenobia. Zenobia comes up from the ground and is promptly stabbed in the foot by the Tonberry and dies. The angry fiend then attacks the party with multiple attacks, one of which is Chef's Knife.
