The Sky-Hook is the first weapon received by Booker in Bioshock Infinite.
It can be used for melee attacks as well as transportation through the Sky-Lines which run throughout the city of Columbia. When riding a Sky-Line, Sky-Hook can be used to deal critical damage to the enemies while on the ground it can be used to deal moderate damage. On weakened enemies the Sky-Hook can be used to perform an devastative executive attack to kill enemies instantly in a gruesome way.
