Lol a diamond blade would be badass. I think that the hidden blade used before Altair got the Apple could be steel. The fact that the metal was rare meant it could be silver. If anything, however, Altair could've just used the Apple to create a new mechanism instead of finding something to craft the blade itself. Vivienne North there's no specfic metal that everyone's armor is made of. Hell, some people just use ballistic, non metal armor. You say something that's stronger than all of them, Well, the only thing stronger than the metal used for armor are rare minerals and metals, at least, most of them.
