Watch as a man gets blind folded and demonstrates his skill. Here’s an excerpt from Wikipedia:
Thang-ta or huyen lallong is a weapon-based Indian martial art created by the Meitei of Manipur. In the Manipuri language, thang means sword and ta means spear. As its name implies, the sword and spear are the primary weapons in thang-ta. The spear can be used in its non-missile form while in close or thrown from afar. Other weapons used include the shield and axe.
