The photohraphs are misleading when held it shows that the bend is lower near the Tang also the colour of the steel is not the normal Shinto colour . Other collectors that have see the sword all go with Koto and one well known collector you may have met in UK goes Koto as well . It can be hard with photographs as the jihada does not show up well on this sword due to bad condition but in hand you can see the details of the  sword better . Thanks for your comment

Acting on advise from a world famous Collector and writer of many best selling Japanese sword books . I do not have the sword with me due to Covid lock down but as soon as I do I will send you more photographs Thanks
