An extremely complicated blade pattern

[Roland_M]

Ian, as far as i know, some high quality antique straight swords from China have a hamon. But i have never seen such a blade, they are seemingly quite rare.

If not repolished, the hamon disappear after a few decades, depending on the quality of forging and heating.

I cannot see, whether there is a hamon or not. This is why i asked for more pictures with flash. Additionally i suggest a careful cleaning with a non-abrasive metal polish.

In my opinion this is not a three layers construction. The border between the outer and inner steel is normally more or less straight or chaotic.
Imho the blade looks like high quality forging.

I like the blade very much.
