i picked up a 'vintage' showa (1926-1988) hatchiwari/kabutowari saturday, on it's way now from japan. roughly 25 in. LOA in the saya, looks about 22 in. out of it , 'blade/hook' about 14.5 in. in mounts and saya. 645grams in saya. metal fittings look untarnished - gold/gold plated? i would assume 'late' showa & more ceremonial than not, tho 645 grams of steel hitting you might smart a bit. pics mostly upside down of course.
. more photos in my
jitte/jutte thread.
