Dainius Posted November 7, 2025 Report Posted November 7, 2025 Hello, I bought a Japanese katana sword. Could you give me some information on whether it is an original sword or a fake? Quote
Ray Singer Posted November 7, 2025 Report Posted November 7, 2025 An authentic antique Japanese sword, with a fake inscription for Inoue Shinkai. If the sword came from an online auction from a dealer in Japan with no papers, unfortunately this is a scenario that often results in purchasing a sword with some prohibitive reason that it is not received kanteisho (authentication papers). 1 1 Quote

Ray Singer Posted November 7, 2025 Report Posted November 7, 2025 This is an authentic Seki made showato arsenal blade, not traditionally made. It has a Seki arsenal stamp. The mei appears to be Noshu Seki ju Hattori Hasahiro saku. Quote
Dainius Posted November 7, 2025 Author Report Posted November 7, 2025 Thanks for the answers, why do you say "non-traditionally made", what do you mean? Quote
Ray Singer Posted November 7, 2025 Report Posted November 7, 2025 It is a type of sword produced during WWII which has some degree of mass production. It is not fully traditionally made. In this case, one difference is that the hamon appears to be have been produced by quenching in oil. Quote
nulldevice Posted November 7, 2025 Report Posted November 7, 2025 2 minutes ago, Dainius said: Thanks for the answers, why do you say "non-traditionally made", what do you mean? Its a wartime (WW2) blade and has a "seki stamp" which is a stamp on the tang of blades that identify they aren't traditionally made. Non-traditionally made typically means they aren't made from tamahagane and they aren't quenched in water (usually oil quenched hamon). There are more nuances beyond this but these are the 2 biggest factors. So if you want a war-time sword, this will fit your objectives. If you wanted a handmade, traditionally made blade made from tamahagane and with a water-quenched hamon, you'll have to look elsewhere. Since you're asking about 2 very different blades in your 2 photos, it might be best to first ask, what are you looking for? 1 Quote

I already know that the signature is fake. Quote
Ray Singer Posted November 7, 2025 Report Posted November 7, 2025 It is a Shinto wakizashi, from the early part of the Edo period. 1 Quote
Dainius Posted November 7, 2025 Author Report Posted November 7, 2025 As far as I understand, this is an original old sword with a fake signature, and do you know what its value could be? Quote
Jacques Posted November 7, 2025 Report Posted November 7, 2025 Quote It is a Shinto wakizashi, from the early part of the Edo period Could be shinshinto even Gendaito. Quote
