The signature wrist weapon of Assassin’s Creed’s Assassins is the hidden blade.
The hidden blade is a retractable blade worn beneath or along the forearm. It is designed for close-range assassination and can be concealed beneath clothing, making it a visual symbol of the Assassin Brotherhood throughout the series.
Altaïr uses an early form of the weapon in the first game, while later protagonists receive mechanical improvements. Leonardo da Vinci upgrades Ezio’s equipment in Assassin’s Creed II, and later versions can include additions such as a poison mechanism, a pistol, or a second blade.
The weapon’s operation and history vary between games. In older lore, an Assassin tradition involved sacrificing a finger to use certain versions safely, but later designs remove that requirement. The hidden blade is therefore distinct from larger weapons such as swords, axes, spears, and the tomahawk used by other protagonists.
