Interesting link to a recently made Ayasugi tanto:

Roland, how did you find that link, simply amazing, I cant believe the amount of work that went into making the steel, the whole process from start to finished blade is really shown here. The video shows that the Japanese physically manipulated the steel billet by cutting into it in order the get the Ayasugi pattern, this is very similar to how some wootz steel patterns were made, I have to assume that the Chinese did something similar when making the twistcore type pattern that is being discussed.



Here is a very good link from Marcus Sesko showing some different Japanese patterns (hada), Marcus has a lot of very informative short essays on many Japanese sword related topics on his site.
