Thanks Josh.
I am familiar with the distinct clipped tip found on "choppers" past and present but this type of wavy curved tip is somewhat of an unknown for me on Chinese edged weapons.
As yet I have not seen, other than yours, a tip of this type except on Koras.
I do hope with a little tenacity, a collective reasearch effort can pin point this style more so. What can a detailed examination of the hilt, guard and peened tang reveal? Is there any evinence suggesting it being rehilted at any stage?
regards
Gavin
