Hidden Blade

"The hidden blade has been a constant companion of ours over the years. Some would say it defines us – and they would not be entirely wrong. Many of our successes would not have been possible without it."

- Altaïr Ibn-La'Ahad's Codex, page 13.



The iconic weapon of the Assassins, the Hidden Blade was 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 protective bracer. As such, the blade could be discreetly extended or retracted, making it a valuable tool for assassinations.

Design
"The blade is designed to ensure the commitment of whoever wields it."

- Leonardo da Vinci, regarding the Hidden Blade.

The use of the Hidden Blade initially required the removal of the user's left ring finger, both as a means of more easily extending the blade, and to show the commitment of the one wielding it. As such, many of the early Levantine Assassins could be recognized by their missing fingers.

However, the blade's mechanism was modified in the 13th century – as outlined in the Codex of Altaïr Ibn-La'Ahad – so as to no longer require such a sacrifice, and to keep Assassins from being identified so easily.

Despite this, the tradition was not forgotten. From the Renaissance to at least the early 20th century, Assassins branded their left ring fingers during their initiation into the Order, as a sign of their devotion to the Creed.

The exact release mechanism of the Hidden Blade is unknown, and while there is a rotating wheel atop the rear portion of the mechanism's housing (one which turns upon the release or retraction of the blade), its function has not yet been identified.

High Middle Ages
The Assassin Altaïr Ibn-La'Ahad initially wielded a Hidden Blade, however, due to his failure in retrieving the 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 Hidden Blade and other weapons. At his promotion to the second rank however, he earned back his Hidden Blade, along with a 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 would usually kill them so that they could not reveal his plans, and did so by burying his Hidden Blade into their abdomen.

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

Renaissance
"Despite its age, the construction is rather advanced. I've never seen anything quite like it."

- Leonardo da Vinci studying the Hidden Blade.

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, and therefore did not require the removal of his ring finger.

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

Ezio Auditore inherited the Hidden Blade from his father 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, so Paola suggested that Ezio ask his ally Leonardo da Vinci to repair it. Fortunately, Leonardo was able to do so, though only 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.

Though Ezio possessed the same two Hidden Blades until 1500, during the Fall of Monteriggioni, he lost most of his weapons, and was only able to salvage the blade and bracer of his father.

Upon his arrival in Rome, Ezio was equipped with a single Hidden Blade, though its bracer had been replaced. Later on, however, Leonardo was again able to reconstruct a secondary Hidden Blade from memory, with Ezio providing him with the money necessary for the raw materials.

Aside from using them in combat, Ezio also made use of his Hidden Blade to pick the locks of certain Lairs of Romulus, and operate the mechanisms within the Temple of Pythagoras.

Additionally, Ezio's apprentices were each equipped with a single Hidden Blade, as the right to use two Hidden Blades was only reserved for the most trusted of Assassins, or those who had earned the rank of Master Assassin. However, upon reaching the rank of Assassino, an apprentice was given a Hidden Blade with a bracer much like Ezio's. Additionally, apprentices were capable of all of the standard assassination techniques.

Modern times
During the late 19th and early 20th century, the Hidden Blade was still part of standard Assassin attire, and continued to be commonly used. Though the Assassins were already using guns, during close combat, the iconic Hidden Blade was occasionally utilized. The Russian Assassin Nikolai Orelov used his Hidden Blade during a battle with Tsar Alexander III, with which he was able to stab the Tsar in the abdomen.

By the late 20th century, Hidden Blades were less commonly used, and were mostly preserved for ceremonies. However, a few high-ranking Assassins still wore one for traditional purposes, such as Paul Bellamy. Daniel Cross was gifted with a ceremonial, but functional, Hidden Blade by the Mentor, which he swiftly put to use, killing the Mentor.

During the escape from the Assassin hideout he was stationed at, Desmond Miles obtained a Hidden Blade and bracer that was almost identical to Ezio's first Hidden Blade. He later used that Hidden Blade to fend off the Abstergo guards who had come to capture him, led by Warren Vidic.

Upon traveling to Monteriggioni, Desmond began using a bare Hidden Blade without a bracer, making it less visible on his arm, though at the cost of some defensive ability. He also used it to operate mechanisms in the tunnels underneath the Sanctuary, as Ezio had once done.

Additionally, in the Animus Virtual Training Program developed by Rebecca Crane, Desmond was given the chance to hone his skills with the Hidden Blade. Such challenges included stealth assassinations and flawless kill streaks using only the Hidden Blade.

High Middle Ages
As it was mainly used for stealth assassinations, the Hidden Blade could only be used in combat under certain conditions, and could not block any attack. Altaïr was only able to assassinate a guard who had fallen on the ground, or had become momentarily distracted.

Altaïr could use the Hidden Blade in a counter-attack; however, the time frame was extremely small, especially in comparison to that of the sword and short blade. Successfully intercepting an enemy attack enabled one of several different – and always lethal – counter-attacks, in which Altaïr stabbed his opponent in the chest, head, abdomen, foot, base of the skull, or spine.

Renaissance
"Now I can kill double the guards."

- Ezio Auditore receiving the second Hidden Blade.



The Hidden Blade eventually became vastly more useful in combat due to several upgrades. The mounting of a metal plate on the opposite side of the blade allowed the Hidden Blade to be used defensively. In terms of offense, when used together, the dual Hidden Blades were a fast but low damage weapon, making them useful for suppressing enemy attacks.

Unlike other weapons, every counter-attack with the Hidden Blades resulted in an instant kill, with only the narrow timing window as a disadvantage. Unlike the sword or short blade, the Hidden Blades could counter attacks from nearly all types of guards, including Brutes, Seekers, and Papal Guards.

The Hidden Blade also gave Ezio more freedom in movement than any other weapon. For example, Ezio could easily strafe to either side while in combat, which was barely possible (except from very close range) with the sword or dagger. It also allowed Ezio to quickly flee from a battle without having to take the time to sheathe his weapon.

By his arrival in Rome, Ezio had gained a greater aptitude with the Hidden Blades. Aside from being able to perform more counter-attacks (due to his improved reaction time) he was now able to perform multiple instant kills after killing a single guard. To continue this "execution streak," each kill needed to be quickly followed up with another, without Ezio being hit in turn.

Codex
"The [Hidden Blade] has begun to show its age – and so I have been researching improvements beyond ending the need to remove one's finger to wield it."

- Altaïr Ibn-La'Ahad's Codex, page 13.

In his studies of the Apple of Eden, Altaïr envisioned several upgrades for the Hidden Blade, which he wrote into his Codex, and some of which he used himself. Throughout Ezio's travels, he would acquire these Codex pages, and Leonardo da Vinci would build the improvements detailed within them for him.

The first of these improvements was the addition of a secondary Hidden Blade, which was attached to the user's other arm, allowing Ezio to kill two guards at once, either on the ground or from the air. 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 Hidden Gun. 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 Hidden Gun allowed Ezio to make a loud but assured kill from a distance.

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

Da Vinci
"I ask if he can arm a crossbow bolt beneath my wrist. He ponders for a moment and declares it possible, but expensive."

- Francesco Vecellio asking Leonardo to create the Hidden Bolt.

Upon his arrival in Rome, Leonardo envisioned further improvements to the Hidden Blade, such as the Poison Dart launcher, which allowed the use of the Poison Blade from a distance.

Leonardo also designed and built the Hidden Bolt, a weapon that could fire small crossbow bolts, upon the request of Francesco Vecellio. As Francesco was only an apprentice at the time, Ezio had not allowed him to use the Hidden Gun, and thus Francesco had devised a similar, though lighter, alternative.

Others
The 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 made use of it in both battle and travel. Primarily, it could be used during navigation in conjunction with ziplines, as well as allow one to perform the "hook-and-run" over enemies, and generally extend one's reach when climbing and leaping.



The Hookblade also aided in combat by allowing a wider variety of attacks or counters, as well as permitting one to "counter-steal" or trip an enemy.

By the late 18th century, another enhancement to the Hidden Blade allowed it to be used as a pivot-based dagger.

The semi-detachable blade could then be used as a more typical hand-held weapon, as well as a skinning knife for hunting, before being returned to a more traditional orientation for use in assassinations.

Replicas
"The assassin leaps! As he lands upon the senator, a weapon protrudes from his wrist. Pierces his victim's neck!"

- Fiora Cavazza observing an Assassin's technique.

In their study of the Assassins' methods and weaponry, several members of the Templar Order created their own variations of the Hidden Blade, though the mechanism and appearance often differed.

The first known instance of this was in the early 16th century, when Fiora Cavazza and Baltasar de Silva tailed the Assassins of Rome, in order to take note of their techniques. They eventually trained Il Lupo in the Assassins' ways, and equipped him with a Switchblade, a Hidden Blade variation whose blade was split into two parts, folding forward only when in use.

Lia de Russo also wore her own Hidden Blade, and though its mechanisms seemed to match that of the Assassins, it was worn on top of her forearm, rather than underneath.

In modern times, during the simulations hosted by the Animi Training Program of Abstergo Industries, every recruit was given access to a variation of the Hidden Blade. The virtual weapon was also worn under the left forearm, but its blade folded along two circular joints when not being used.

Trivia

 * Design
 * Patrice Désilets, the creative director of the game, stated that the addition of a second blade in Assassin's Creed II also had a lucid reason: "it's Assassin's Creed II, so there [were] two blades."
 * Assassin's Creed: Renaissance and early concept art for Assassin's Creed II showed Ezio possessing three Hidden Blades; one on his right, and two on his left.
 * The original design of Ezio's second Hidden Blade in Assassin's Creed II was displayed as a brown glove, however, in-game, it was replaced with a second bracer. This was reverted in Assassin's Creed: Brotherhood however, where his second Hidden Blade included a glove, until a bracer was purchased.
 * Concept art for the "Shock Blade", a modern version of the Hidden Blade, was shown in the Assassin's Creed Encyclopedia.
 * It is unknown why the Assassin's Creed: Brotherhood box art, E3 Trailer and other official media depicted Ezio with a secondary Hidden Blade bracer that was identical to his primary one, as in-game, no such second bracer exists.
 * The second Hidden Blade is marginally longer than the primary one in Assassin's Creed: Brotherhood.
 * One concept art by Martin Deschambault for Assassin's Creed II showed two unimplemented Hidden Blade upgrades; a retracting arrow-shaped blade, and a retracting trident-ended blade for parrying weapons and disarming enemies.
 * Martin Deschambault's art also shows two designs of the blade itself; feather-look, and normal blade with designed holes.


 * Mechanism
 * In the E3 teaser trailer of Assassin's Creed (as well as in certain concept art), Altaïr can be seen pushing a button to operate his Hidden Blade. In the actual games, however, no such button or other trigger mechanism exists.
 * In Assassin's Creed: Renaissance and the Assassin's Creed: Brotherhood novel, unleashing the Hidden Blade required the use of a button, via a certain muscle on the forearm being flexed.
 * The same mechanism also triggered the Hidden Gun if the user's thumb was pushed to the left.
 * In an Assassin's Creed Developer Diary video, Jade Raymond spoke about the lack of Altaïr's ring finger and the Assassins' initiation ceremony.
 * The Hidden Blade is a crafted item in Assassin's Creed: Project Legacy. The materials for its construction are 2 Coils, 1 Iron, 1 Hide and 1 Box of Components (which in turn is crafted using 3 Gears, 3 Screws, 1 Chain and 2 Sprockets).
 * In Assassin's Creed: The Secret Crusade, the trigger mechanism was depicted as a ring worn around a finger. Movement of that finger would cause the blade to extend or retract.


 * Others
 * In Assassin's Creed, despite being equipped with a Hidden Blade, some Assassins (such as Malik Al-Sayf) do not have an amputated finger. This error was later corrected in Assassin's Creed: Revelations.
 * The first recorded usage of the Hidden Blade by an Assassin was by Darius, when he assassinated Xerxes of Persia. However, his ring finger remained intact and he wielded it on his right hand.
 * In Assassin's Creed, the Hidden Blade is used in every major assassination. Even if an Assassin began by attacking their target with a sword, they would always finish them off with the hidden blade. Later however, it was changed so that they could use any weapon they wished.
 * In Assassin's Creed: Bloodlines, if the PlayStation Portable was linked to Assassins Creed II, Altaïr's Hidden Blade could be upgraded to be able to block light and heavy attacks.
 * In Assassin's Creed: Altaïr's Chronicles, Altaïr could only use the Hidden Blade to assassinate an enemy from behind, if it is related to the story.
 * There is a glitch in the Assassin's Creed II mission "Practice What You Preach." If Ezio went to the blacksmith and purchased the Leather Vambrace, instead of practicing the new assassination techniques, he could acquire the second Hidden Blade before Leonardo even made it for him.
 * In Assassin's Creed: Embers, the Chinese Assassin Shao Jun uses a modified Hidden Blade, located along the sole of her shoe.
 * The Hidden Blade can be used in Valve's Team Fortress 2 under the name Sharp Dresser. It was available for those who pre-ordered Assassin's Creed: Revelations on Steam before December 2, 2011.
