I restored a small Masamoto 210mm Yanagi fr. a friend who bought it in Japan.He said it came in a box,that he didn't keep.Told him usually wt. quality Yanagi's come wt. saya sometimes under the cardboard that the knife sits on.
Anyway had a hard time finding a 210mm Yanagi saya.Found one,but it is too tight.With force I can push the Yanagi all the way in & it clears the saya pin hole.It is hard to get the blade out.
The binding is as the knife gets thicker toward the handle about one inch fr. the horn collar,so the entrance part of saya needs to be widened.
Thinking of putting the saya in a vise & use small thin carbon wood chisels I have.
Any other suggestions on how to fix this?
