Hook Blades are the signature bladed weapons which were used by some members of the Skull Creatures and objects in the BIONICLE universe. These swords are known to be wielded by the Skull Warriors and Skull Slicer, although they are also wielded by Kulta at the same time.
The Hook Blades can be used to cut through solid stone with ease and can also hook onto the masks of their opponents to pry them off.
