The Khans are marked with unique cultural heritage and features within their traditional craftsmanship. One such artifact that they can proudly claim is the curve dao, now preserved in the Indian Museum, Kolkata. This traditional dao comprises a long curved iron blade with a sharp cutting edge that bends inward toward the blunt edge, a design suited for slashing and clearing vegetation in the hilly terrain of Meghalaya.
The blade becomes gradually wider toward the top, and the top itself is broad and slightly curved inwards, giving the dao a powerful and balanced form. A long, flat wooden handle is fixed with the blade so that the grip remains tight while working and its usage becomes effortless.
At the upper end of the handle, a plaited cane band circles it, adding further cultural and aesthetic appeal, reinforcing it in terms of strength and picking some traditional Khasi decorative styles.
The whole structure thus involves eco-friendly materials, viz., wood and cane. This emphasizes the sustainable living of the tribe and its relation to nature. Traditionally, such daos were not only tools for farming and forest work, but they also had symbolic and memorial importance among the Khasi people. This dao is a testimony to the creativity, endurance, and artistry of the Khasi people.
