It is briefly seen and used twice. At this time, it is extremely simple. It is composed of a few pieces of designed metal, with small guiding hooks and a wheel to slide on the Sky-Line. This design appears very weak compared to the wear expected of it.

At E3, much more developed version is shown, although it is still called the Prototype Sky-Hook. Ken Levine announced a contest for a real version of it in a one-of-a-kind case, seen below.

During the gameplay video, Booker is seen using the Sky-Hook on numerous occasions, frequently hopping between Sky-Lines in order to first reach a Security Zeppelin, and then to return to Elizabeth. Unlike the rest of Booker's arsenal, this tool is passively equipped and cannot be switched out for another weapon.

In the Beast of America trailer, a Vox Populi member is seen sawing into the head of a policeman in a somewhat graphic display of violence.
