Thanks Norm! there not that many about with full length decoration.
Yep thats the type of tang Jurrassic, & it may indeed be a danger if the hole is drilled in & just full of laha.
But I have Never yet seen a traditional kukri over 70 years old that was drilled though.
They used to carve the hole in the grip to match the tang, & in good quality pieces the lower side of the tang was also curved that helps provide a locking action that when fitted that wont allow the blade to come out in use unless the handle splits allong both of the sides to allow movement. When handles are fitted this way deep cracks seem rare. The close fit provides strength. I think bolsters had to become more of a ferrule as the tang holes got bigger perhaps?
Those I have dissisembled need to be pulled forward & downwouds in a curving action to remove the blade, even when the laha is melted.
So the blade isnt going to fly!
I have loads with traditional handles on kukri over 100 years old that Id trust my life to.
My main current user takes a real hammering & has this type of tang in a horn handle. {& it hasnt even got a real bolster because some idiot chiseled it off.} Id guess its handle & scabbard is 1920s or earlier. Blade might be much older though. Some idiot chiseled the bolster off it though for the scrap value.:jerkit:
