Hookblade

The Hookblade is a new tool introduced in Assassin's Creed: Revelations.

Gameplay
The Hookblade was designed to make navigation through busy districts quicker and easier, where in Ezio can use it to attach to ziplines in the citys he explores and is said to make navigation faster by 30%. However, the Hookblade is not only a tool but a useful weapon in combat, where Ezio can use it to pull enemys in for a combo, how this works and is done is currently unknown.

Design
The Hookblade is appearntly attatched to Ezio's hidden blade, having has a golden color, which may mean it is forged from solid rock gold.
