Looking at it historically, it cannot be Titanium as it was discovered only in 1791..although in the AC Universe, anything's possible and the Assassins could have found a very reliable, strong metal that is light to carry but generates enough pressure to penetrate strong armors...Also, no mention that Leonardo changed anything in the setup other than making it accessible without having to cut a finger...just accept the fact that Assassins are badasses mate...they can go through anything.... Adamantum is just plain wrong...may be w::c:marvel-cinematic-universe:Vibranium?:P
