Walosi I think Uncle Bill told us one time that the kamis make a sheet metal pattern and write "notes" only they can understand on them for each khukuri they make.
Not exactly a blueprint so to speak, but never the less a pattern to keep them in the ball park.
And that's why a wood or other 3-D model is required to get close to what you want on a special order.
The 3-D model makes up for their "notes" as to width, fullers and other details they put on the flat sheet metal patterns.
When Jim March took his old Japanese Katana to the Cantina he told about
Pala,(Kami Sherpa), making a drawing of it that he couldn't understand how the information was translated since it was nothing of the sort we would draw to make anything.
IIRC that was when it was decided to actualy let Pala take the katana back home with him for a model for the H.I.Everest Katana.
It kind of upset a few people when the kamis took the old katana too an anvil and started pounding on the tang erasing the signature of the Japanese maker of so long ago.
Jim said the katana had rust on the blade and that the blade was tired as well and not worth spending the money for a repolish, again IIRC.
