Dha (sword)

Dha (also spelled dah or dhaw) is the Burmese word for "knife." The term dha is conventionally used refer to a wide variety of knives and swords used by many people across Indochina, especially present-day Myanmar (Burma), Thailand, Yunnan, Laos, Cambodia and Vietnam.

Origins
The broad use and diffusion of the dha across Southeast Asia makes it difficult to attribute a definitive origin. The Burmese moved into Southeast Asia from the northwest (present day India), passing thought Assam, including a region dominated by the Naga people called Nagaland. The dha and its variants were possibly derived from the Naga dao, a broadsword used by the Naga people of northeast India for digging as well as killing. The Naga weapon was a thick, heavy, eighteen-inch long backsword with a bevel instead of a point, and this form of blade is found on some dha. Alternatively, the dha may have its origins with the Tai people who migrated to the area from what we know today as Yunnan Province in southern China. The Khmer and Mon peoples were well established before the arrival the Tai or the Burmese people; perhaps they invented the dha (13th-century reliefs discovered at Angkor depict dha). The history of the region includes many periods where one or the other of these groups dominated, bringing along their culture, including their weapons, to conquered areas.

Similar terms exist in the surrounding area with slightly different meanings. The Chinese word dao (pronounced tou in Cantonese) means knife but can refer to any bladed weapon with only one edge. In Bengali, a dao is a six inch long knife. From the Himalayas, the dao spread to Southeast Asia where it came into its present shape. While it is pronounced dha in Burmese, among Khmer-speakers it is known as dao and some believe it is related to the Malay words pedang and sundang, meaning sword. The dha itself is called krabi in Thai, but the equivalent Thai term is daab (ดาบ) which usually refers to a straight double-edge sword. A related term, dap, means a long-handled sword in Malay.

Anatomy
Dha vary considerably according to locality but they share a few features the define them apart from other weapons and tools of the area. These features are a round cross-section grip, a long, gently curving blade (sometimes upward, other times downward in the direction of use) with a single edge, and no guard. Knives and swords with these characteristics are viewed by ethnic groups of the region as being of a single type, albeit with variations arising from local style and tradition. There are a large number of possible shapes for the tip, with upswept, downswept, squared-off and spear-like varieties all being found. The blades are often inscribed, which can range from a simple maker's mark to quite intricate designs that may also feature inlays.

Hilts range from hand-width to quite long. A blade/hilt length ratio of 2:1 is not uncommon. Despite these long handles, most dha are meant for single-handed use, although some two-handed weapons exist. Guards are small, if present at all. Thai daab may have a guard similar to the tsuba of the Japanese katana. The montagnard dha may have a guard that barely exceeds the diameter of the handle and they can be regarded more as a spacer. The construction of the hilt varies widely by type and region or origin. Hilts range from simple wood, possibly wrapped in rattan or covered in ray skin, to elaborately worked silver and ivory. Pommels may or may not be present. Scabbards are made from two strips of wood, often bamboo, secured by metal bands, rattan (e.g., "village" dha), or completely wrapped in metal
