Isn't there more to IDing the origin of this blade than simply the blade profile? There are, after all, only so many logic blade profiles in the world of edged weapons and we see similarities in weapons from all over the world. What about other aspects of the blade design? For instance, i do NOT see the bolster that is obvious on Andrew's Thai example on Detlef's blade. And if we are going to look closely at just the blade profile, Detlef's spine is much straighter across than any of these other examples and it possesses something like "aring" sticking out at the base on the edge side that does not appear in the Thai examples.
