What it is

Blades forged from Indian crucible steel (wootz) ingots, with wavy patterns and an exceptional edge thanks to aligned carbides. A symbol of Islamic metallurgical superiority.

The name may derive from Damascus as a place of sale rather than manufacture; the exact technique was lost around 1750 and remains debated.

What it led to

  • Afro-Eurasian trade in steel ingots between India, Persia and Syria
  • the military reputation and prestige of Islamic swords
  • European attempts at imitation (pattern-welded steel) and 19th-century metallurgical studies
