The iconic weapon of the Assassins, the Hidden Blade was a weapon used for both stealth assassinations and regular combat. It was their most versatile weapon, with multiple upgrades and forms of use.

It consisted of a retractable blade, usually in conjunction with a bracer, which could be discretely extended or retracted; making it a valuable tool for assassinations. It was commonly worn on the user's left arm.


Third CrusadeEdit

The Assassin Altaïr Ibn-La'Ahad initially wielded a hidden blade, however, due to his failure in retrieving the
AC Hidden Bade
Apple of Eden, and his breaking of all three tenets of the Creed, he was demoted to a Novice by Al Mualim, and was stripped of his weapons. At his first promotion to the second rank however, he earned back his hidden blade, along with his sword.

Aside from assassinations, the hidden blade was also used in a variety of investigations. For missions given by informants, wherein Altaïr was asked to stealthily assassinate a number of targets, he could only make use of his hidden blade or throwing knives in order to remain undetected. Additionally, after successfully interrogating a target, Altaïr was forced to kill them so they could not reveal his plans, and did so by burying his hidden blade into their abdomen.

Although the blade was used mainly for stealth, it could also be used in open conflict, but only for countering enemy attacks.


In his own time as an Assassin, Giovanni Auditore also wielded a hidden blade, albeit one that had been adapted to the change of the times. As outlined in the Codex, the revised blade had been designed by Altaïr so that the Assassins, who he intended to go undercover, could not be identified by their lack of a ring finger.

Furthermore, the mechanism did not require a wrist "flick" to extend the blade, thus the user could retract the blade without any wrist or hand movement. Additionally, as pictured, the weapon could be used with a clenched fist, although Giovanni is one of the few known Assassins to use it in that manner.

While there is a rotating wheel atop the rear portion of the mechanism's housing (one which turns upon releasing or retracting the blade), its function has not been identified, and there are no known schematics or explanations for the mechanism.

Ezio Auditore inherited the hidden blade from his father, along with his Assassin's robe, the night before the Auditore execution. However, the blade was broken due to Giovanni's last fight in Rome against Rodrigo Borgia and his men, thus Paola suggested that Ezio ask Leonardo da Vinci to repair it. Leonardo was able to do so, with the aid of the schematics detailed in the Codex.

Through other Codex pages, Leonardo was able to provide Ezio with a variety of upgrades; such as the addition of a second hidden blade. Ezio made use of these innovations for the majority of his assassinations, and was also able to wield them in battle.


Throughout his travels, Ezio would acquire several Codex pages that, upon decryption, detailed upgrades for the hidden blade that were envisioned by Altaïr. These improvements were then built for Ezio by Leonardo da Vinci.

The first of these improvements was the addition of a second hidden blade, which was attached to the user's other arm. The second was a metal plate on top of the primary blade's bracer that allowed one to safely deflect enemy attacks with the blades.

Other Codex upgrades included the poison blade and pistol. The poison blade allowed Ezio to stab an enemy and leave them to die slowly, granting both a low-profile assassination as well as a distraction to kill or bypass other enemies, while the pistol allowed Ezio to kill from a distance.

Additionally, both blades could be supplemented with various vambraces, which acted as protective armor.

The Hook BladeEdit

The Hidden Blade Hookblade was a modification of the hidden blade that was adopted by the Assassins guild of Constantinople. Unlike the other hidden blade advancements, it was attached to the user's secondary hidden blade, instead of the primary.

Upon his arrival in the city, Ezio also adopted it for use in both battle and travel, by using Ziplines installed across the city rooftops.
