Nice forging and Dha interpretation
In deed, old blades do use fold steel. In the old day,though ,forge folding do not show any pattern, its main purpose are slag reduction and surface carburizing. I just finish electroclean a blade which has a sign of fold steel. Will post a pic in our previous fold steel thread.
Typical Dha blades do not have prominent ricasso. Their tang 's forced into the ferrule-encased hilt. I do like the integral ricasso like this as long as the integral part 's not so heavy that its balance point move too much backward. A little bigger (thicker and longer) ricasso would be nice for its appearance could be similar to typical ferrule (Dama pattern is a plus
).
Traditional Dha 's flat or slightly convex ground with little or no bevel. Your one looks fine (with a bit westernized feel
).
It would be nice to have the hilt upward (Lanna style) or downward (Burman style). A hardwood hilt on this kind of blade usually has (profiled) round butt rather than Tanto style cut-off butt
. You can also visit Mark's page and study his sample. He has a superb collection of Burman knives and Dha(s).
