The 1878 & 1951 catalogue do not included the so called Kachin dha or dah.

In your experience Ian what percentage of pre.1950 dha are monosteel or shear steel, compared to the laminated & hairpin patterns?

Spiral, the Kachin "sword-dao" with the flared pommel and flared, flat tips are often laminated steel.

Of the swords we collectively refer to as "dah", "dha", or "daab", I have only seen a handful with obvious laminate construction prior to etching. One such is pictured below, with the Burmese date of 1242 Chulasakarat (1880 C.E.) inlaid at the forte in gold (previously believed to be brass). The blade is extremely thin, for this type of weapon, light, flexible and razor-sharp. One of the finest Continental SEA sword blades I have ever seen. It also appears in an early W.D. Oldman catalog.

Many (even most) have differentially-hardened edges. Some have inserted edges similar to Chinese san-mei, and I have one very fine example that exhibits a crystalline structure when etched/polished I would like to believe is crucible-steel (but more likely shear ).
