@Ray Singer it's true I can guess it is there when looking at the pictures but I cannot while looking for it with my eyes... I mean, the hamon is clearly seen unlike the boshi. Polisher fault? Nihonto fault? Maybe smith's fault or even my own?
Are you seeing the kaeri? Because I'm not... I'll try to get better pictures tomorrow anyway.
About the kissaki, I do not think it has been reshaped, what is your opinion on that matter?
Thank you very much for taking the time to answer. It's really appreciated.
