The Khasi dao is a peculiar type of two-handed, single-edged sword with all-steel construction and double crossguards. It is named after the Khasi people of the Khasi hills but was in wider use in the region.

The general Khasi word for sword is waitlam and these swords were known as waitsum, literally "spear sword".1

Similar swords have been observed in use by the Ao Nagas as part of a larger group of archaic large sword forms used in ceremonies.2

Similar blade of the Tang dynasty

The blade shape appears as early as the Tang dynasty, carried by tribute bearers of unknown origin.

By the time foreign observers encountered them, they had already fallen out of practical use and were passed down as heirlooms in wealthy families.

Among the Ao Nagas, the swords only came out only three times a year, during sacrificial ceremonies for good harvest where a mithan, a forest-dwelling buffalo, was sacrificed to the Gods. A pair of these swords were put in the ground upright during the ceremony, and it was considered a bad omen if one of them toppled over.3

The Lotha Naga use the term yanthang for a group of large antiquated swords used for the same ritual purposes.4

2. Philip S. Rawson; The Indian Sword. London, Herbert Jenkins. 1968. Page 62. Rawson also attributes the weapon to the Lotha Nagas, the Mikirs, and the Bodo but following his footnotes, I did not see this confirmed. The Lotha for example do use large, antiquated dao for ceremonies but they are of a distinctly different type. See the relevant pages for; LothaMikirs, and Bodo.

In the literature

"These arms of the Khasi-Jyntia tribes are as peculiar as their language.
"The tiny family of Khasi is like an island in the midst of the Tibeto-Burman Sea." - (Robt. Cust, Languages of the E. Indies, p.4.)."

-Lord Egerton of Tatton, 1880


"The weapons of the Khasis are swords, spears, bows and arrows, and a circular shield which was used formerly for purposes of defence. The swords are usually of wrought iron, occasionally of steel, and are forged in the local smithies. The Khasi sword is of considerable length, and possesses the peculiarity of not having a handle of different material from that which is used for the blade. In the Khasi sword the handle is never made of wood or bone, or of anything except iron or steel, the result being that the sword is most awkward to hold, and could never have been of much use as a weapon of offence." 2

-Major Philip Richard Thornhagh Gurdon, 1907


Describing their use among the Ao Nagas of Mokokchung:

"Besides these "daos", examples of which are still to be seen from time to time, there are kept in the houses of a few rich men ancient long "daos" (noklang C and M) of unknown origin, which are handed down as heirlooms.

These may be divided into three types, all alike having very long tangs which must have passed right through the haft, so that the "dao" could be stuck upright in the ground. Indeed it is in this way that they are displayed at mithan sacrifices, the only time, apparently, when they are brought out of the house." 3

-James Philip Mills, 1926
