Just asking a question about the name of these knives, is it hmong or enep?
I too have one example of these knives and seeing that there are not that many shown on the forum I thought I would add it here as well. Instead of a wooden scabbard mine has one made of rattan similar to the second one down in Kronckews photo. Unlike the others shown above it also has some designs stamped into each side of the blade. Sorry about the very poor photo quality, but at the present these are the only ones that I have.
Best,
Robert
