Damascus Steel

Alloys · Rare · Medieval

Blades from the medieval Middle East, forged from wootz ingots imported from India, with a watered pattern in the steel that no European smith could reproduce. The method depended on trace impurities in one particular ore, and when that ore ran out around 1750 the craft went with it. What smiths sell as damascus today is pattern-welded steel, a different thing that looks similar.

Identity

Source: Middle Eastern smithing tradition
Composition: Iron, Carbon ~1-1.5%
Over time: Historical Damascus blades were forged in the Near East from wootz crucible steel ingots brought from southern India. The modern knife steel sold as damascus is pattern-welded: layers of different steels forged together, another technique altogether.
Also known as: Wootz steel (source material)
Ores, before industry and since: Goethite (Iron), Hematite (Iron), Limonite (Iron), Magnetite (Iron), Siderite (Iron)

Lore & Narrative

Crusader accounts describe Damascus blades cutting falling silk and shaving hair, feats modern replications can confirm. The flowing patterns are formed by carbide bands of cementite, created through repeated folding and acid etching.
