Japanese blade

[CNK1]

Good morning friends,

Thank's for your help !

Unfortunately I think Timo said all about this blade, this is probably a copy !

I bought it to a non-collector but it's not a guarantee of authenticity, fortunately I haven't paid high price so this is the price of the knowledge

So thank's again to share your knowledge with me, it's everytime a great pleasure to learn !

Best regards,
Clement
