I am not sure if I should post this here or in the Military swords forum as it has a foot in both camps (so I’ve posted it in both…hope that is ok) It is not a military sword but is (I think/hope) by a good Showa smith. If I have got it right it is signed “Seki ju nin Watanabe Kanenaga Saku”and dated 1937. It is in terrible polish….remains of perpendicular scratches etc and is in a shirasaya that someone has adapted to hold it. There is thankfully no serious damage though. They are not great ima
