Hi Stan,
I don't know if you've already dropped your bhuj in the mail for its return journey, but FWIW, I am of the opinion the design of the weapon is inherently flawed, and in my own lone example, there is a little 'battle rattle' at the join between the blade and the hilt, IMO a natural consequence of securing a short (or virtually no) tang blade to the haft with a single rivet...
