I have just run across some interesting items.
The grip appears to made from a travelling brush/pen inkwell thingy (picture attached) with the inkwell part cut off. A brass finger guard repurposed for the front & the blade inserted. The pommel does not have a peened tang, just the original brush tube cap. Not sure where the brass finger guard came from.
I've found the blade is very similar to those made in Yunnan province for Burmese Dhas, and might also be from there for Chinese style Dao.
19.5" blade, 1 in. wide , 3/8" thick at grip (1/4" at 1" from grip) distal taper to 1/8" at tip, concaved blade spine to halfway, then spine is grooved either side to the tip, single fuller runs the full length. blade tip may have been shortened, but early yunnan dhas had a tip like that.
Mine appears to be a marriage made for a western buyer (or a chinese pirate

). I've removed the leather thong wrap someone added later.
