Iron Fist Icon

The Kaiser Knuckle, also known as Iron Fist, is a cestus in the Castlevania series. They are knuckles imbued with divine rage.


The Kaiser Knuckle is a knuckle band that sometimes can be equipped on the arm, sometimes as armor, and sometimes as a fist weapon. When used as a fist weapon, it allows a flurry of punches to be performed. The weapon is oftentimes associated with the Werewolf, which has the ability to punch fast (although not as fast as the Kaiser Knuckle). The Sacred Fist sub-weapon in Castlevania: Harmony of Dissonance is somewhat similar to the Kaiser Knuckle, although it extends Juste's range considerably.

In Castlevania: Harmony of Dissonance, it grants +3 STR in addition to +3 DEF. This is better than a regular Bangle, which does not give the STR boost, but less effective than the Silver Bangle, which gives +20 DEF.

The Kaiser Knuckle is the most powerful of the two cestuses in Castlevania: Harmony of Despair that both Alucard and Soma Cruz are able to use (the other being the weak Knuckle Duster). It is the second most powerful cestus for both of them, being less powerful than the Whip Knuckle for Soma and the Fist of Tulkas for Alucard.
