Naval Wakizashi?

[DTM72]

May be odd, maybe not. I have seen family wakizashi in Army and Navy mounts, but never seen a stainless anchor stamped version. Nagasa is 22" (55.8 cm). All numbers on small seppa, large ray seppa, tsuba, fuchi, and habaki match.

Dan this is by far the nicest of the swords so far, and most interesting. Showa era Wakizashi are rare, a stainless example is even more unusual.

So if this is unusual, that makes 3 out of 4 that are unusual. The fourth being the "last ditch" NCO.

The old gentleman I bought these from is holding on to his father's kai-gunto. It is signed 特殊鋼以井戸秀俊作 which is Tokushu-kō motte Ido Hidetoshi saku. The first part, Tokushu-kō Motte is "Special Steel Mix". Best I have researched, and what I see in person is that it is a mix of stainless and carbon steel.

He has owned all these swords for 35 years, when his father gave them to him. His father got the kai-gunto while fighting in Guadal-Canal. The others he got while stationed in Tokyo from 1945-1946.
