And here I thought machi was the whole neck... good grief
Funny how 'handle' is the same in both languages
Maybe I don't understand all of the terms, but I would disagree with some of those. I don't see any choil on the knife (although maybe you could call it that) and I would call K the ricasso. Is machi the tang or the shoulders of the ricasso? And shinogi primary bevel (naming from the spine)?
Japanese knife terminology differs from Western. Machi is the gap between emoto (neck) and front of the tuka (handle) where a tiny bit of the tang is exposed. Not all knife makers incorporate this feature into their product. The shinogi is the demarcation line between the tsura (face) and the kireha (blade road). These terms are usually associated with traditional 'single bevel' knives only.

So shinogi is the line where the faces meet, is kiriba/kireha the primary bevel then or is something else meant by "blade road"?
