Haladie

The haladie is a double-edged dagger from ancient India, consisting of two curved blades, each approximately 8.5 in in length, attached to a single hilt.

The weapon was used by warriors of the Indian Rajput clans, and was both a stabbing and slicing blade. Some haladie had spikes on one side of the handle in the style of a knuckle duster, while others had a third blade in this position. In some cases the main blades would be serrated.

Eventually, the haladie began to be used outside of India, most notably in Syria.

The haladie is believed to be one of the world's first triple-edged blades.
