Hello Nathaniel
Without actual measurements I'm guessing the blade is a big one. 18 in?
If so I would guess that kukri was made for ritual use at festivals such as daishan. Kukri looks well made perhaps 1920s to 40s

My speculations may be off track as I am not familiar with this type. Others will know more.
Is it possible to tell if the decoration was filled with any other material?
Thanks for sharing Nathaniel.
Best regards,
Daniel
