In the Persian epic poem Amir Arsalan, what kind of weapon is Shamshir-e Zomorrodnegār?
Shamshir-e Zomorrodnegar Shamshir-e Zomorrodnegār (Persian: شمشیر زمردنگار, 'the emerald-studded sword') is a sword in the Persian legend Amir Arsalan. The witch mother of a hideous horned demon called Fulad-zereh used a charm to make his body invulnerable to all weapons except this specific sword.
Urumi The urumi (Malayalam: ഉറുമി, "urumi"; Tamil: உறுமி, "urumi", Sinhalese: එතුණු කඩුව "ethunu kaduwa"; Hindi: "āra") is a sword with a flexible whip-like blade from the Indian subcontinent. Originating in what are now southern India and Sri Lanka, it is thought to have existed as far back as the Maurya Empire. It is considered one of the most difficult weapons to master due to the risk of injuring oneself. It is treated as a steel whip, and therefore requires prior knowledge of that weapon as well as the sword. For this reason, the urumi is always taught last in Indian martial arts.
