Iron Bamboo
ItemIron bamboo is an early crafting material from which the military once fashioned its weapons and gear, including the throwaway blades used with vertical maneuvering gear, before ultrahard steel gradually took its place.
Overview
Iron bamboo belongs to an older generation of military technology within the Walls. Before modern alloys arrived, this substance served as the raw material for weapons and equipment used by humanity's soldiers.
Function
Its signature application is the disposable blades carried on the vertical maneuvering equipment, the swords soldiers burn through while fighting Titans. As metallurgy advances, iron bamboo is progressively retired from blade-making, with ultrahard steel ultimately supplanting it. The material survives in a secondary role: the canisters that store iceburst stone for maneuvering gear are fashioned from it.
Notable Users
The Survey Corps is the branch recorded as relying on gear crafted from iron bamboo during the material's era of use. Ultrahard steel itself carries the older material forward, since the newer alloy is forged from a blend of iron bamboo and rare metals to gain both strength and lightness.
