Side point, but I'd like to point out a much cheaper weapon, Cold Steel's
"Two-handed kukri machete." Although I don't know how the bhuj balances, the two designs are broadly similar.
If you watch the video, you see that the machete can be thrown like a spear, so I suspect a bhuj could be thrown as well. Personally, I'd suggest that it might be better to experiment with the two-handed kuk than with an antique, if anyone wants to do some experiments....
My 0.002 cents,
