What is the name of the hidden blade's wrist-mounted weapon in Assassin's Creed?

The wrist-mounted weapon is called the Hidden Blade in Assassin's Creed.

The Hidden Blade is the signature close-range weapon of the Assassins. It is concealed beneath a sleeve and can be extended for discreet attacks, making it closely associated with the series' social-stealth approach. Different games add variations, upgrades, or extra functions, but the core weapon retains the same name.

The weapon appears in the original Assassin's Creed and remains a recurring symbol throughout the franchise. Its use is often tied to assassination animations, though later games also allow it to support combat, traversal, or utility mechanics depending on the protagonist and era.

Some related weapons have different names. Assassin's Creed Unity features the Phantom Blade, a concealed ranged weapon, while Assassin's Creed Revelations introduces a Hookblade that expands climbing and traversal options. Those are separate devices; the classic retractable wrist weapon is the Hidden Blade.
