Masamoto KS 210mm Kamagata Usuba Horn ferrule - $210 shipped CONUS 48 states.
Used once to test cut, never sharpened, bought in Japan a few years back in Kappabashi.
Wondering what the end result was for the OP. Looking to get my mom a new knife. As she gets older I'm think a smaller, nimbler knife may be preferable to something too big like a 240 gyuto.
