Hello Bill,
Yes, I've seen this approach to repair a broken tang quite a few times - seems to hold amazingly well even in battle...
I'm looking forward to seeing this kris restored to full glory! (While the repair is genuine, the grip "wrap" certainly isn't Moro!
That one can only get better...
)
I'd appreciate if you could post pics of the disassembled pieces - one doesn't get an opportunity to study these as easily as in keris.
Regards,
Kai
