First a disclaimer. I bought this when I started collecting swords before I settled on European Military as my main area of interest. I didn’t know much but wanted some real Nihonto. This didn’t cost a lot so I accepted poor quality as long as it was a traditional blade. This had a huge chip in the edge and as I lacked appreciation of Japanese swords I polished it out. I know better now. Please feel free to criticise my actions but be aware I now understand my transgressions. That out of the way what can people tell me about this tanto? Signed Naoyoshi ( 1818-1865 Mikawa, Son of the 6th generation Mishina Naomichi?)

The blade had a large chip on edge towards mid blade. Did not completely destroy hamon so polished out. Hamon very narrow. One flaw on edge on one side of the blade but does not go through to the other side. Some activity in the blade but the hada which seems to have a wave pattern is difficult to see or photograph. (I have done my best with a usb microscope)There is a very narrow Suguha hamon Scratch pattern gilt habaki. Sageo is modern silk addition. I like this tanto so I don't mind if I'm told it is worthless or ruined, I will be keeping it as an example of a genuine Nihonto (I hope) Pics with green background are the blade as purchased.
