The Assassin's Creed franchise is filled with memorable iconography, from the signature symbol of the Brotherhood, to the distinct hoods that each assassin uses to hide their face. If one thing stands out the most, however, it's the franchise's signature weapon: the hidden blade. This unique assassination tool has been at the heart of the series since the very first Assassin's Creed game, dazzling fans with its clever design. AC likely wouldn't be the same without the hidden blade, and Ubisoft has spent the better part of 16 years turning it into one of the most recognizable video game weapons ever.
