Yusuke stainless, what type of steel is it?

[dafox]

I'm assuming its 13c26, AEB-L, it's described as Swedish stainless and is sometimes offered with extra hardness, hrc61. Other thoughts?

Could be AEB-H/19C27 which is called “swedish steel” too but “extra hard” of 61 makes me lean towards 13C26

I have zero evidence but was led to believe it was 19C27. It was my understanding the extra hard and extra thick/thin versions were the knives from batches that were outside of the normal variances. A beneficial error.

In the end it didn't matter what stainless it was to me. It sharpened easy enough and had good edge retention for home use. The Sakai Yusuke knives remind me of Ashi Ginga's. This is just a feeling on my part having owned both.
