you dont
If I tell you, it will no longer be hidden.
If your talking about in the Assassins creed series, no where, there is no such thing as a "third" hidden blade, only in script modifications. If your talking about real hidden blades, just make one.
In the game: You get it after talking to Giovanni, lose it, then is recovered by Paloa. In real life: Buy a 12" locking mechanism, and a knife. Assemble them together.
Try the animus
In the real world, there was no hidden blade. However, there were katars (or katara), which were basically the same thing. In the Assassin's Creed time line, it was Darius, the assassin of Xerxes I of Persia.
No. Although it would've been a novel weapon for an assassin during the Crusades, no such weapon existed. All blueprints drawn for the weapon were created by Ubisoft Montreal, the game's designer.
no stupid personnn
The hidden blade as shown within the game is a fantasy weapon. While it may be backed by some mechanical work, designing one with the identical use and look may be impossible. Official concept art of Altair's hidden blade show a mechanism similar to a scissor lift, activated by the tug of pinky ring. Ezio's blade is a different style and most likely operates on a system of springs and locks.
In real life no unless there is some kinda portal or jutsu that sends u there in naruto fiction world yes obviosly
