Tetsujin Blue 2 Kasumi is the little brother of the well-known Tanryusen line. Offering the same profile, same grind, same steel, except the foriging cloud of the Tanryusen. Same as Tanryusen, this Blue 2 Kasumi line is forged by by Toru Tamura (田村 徹) and sharpened by Naohito Myojin (明神 直人)

======

Naohito Myojin (明神 直人) is a young sharpener based in Kochi prefecture. While his workshop Myojin Riki Seisakusho is probably not as famous as the established brands from Sakai and Echizen, he is the sharpener behind some of the very famous knife lines in the industry; noteabley the Tetsujin brand and the 'Fujiyama' line by Konosuke. 

I think 'refined' is the best word to describe Naohito's work: while featuring proven cutting performance, his knife has some of the best finishes out there. The spine is nicely chamfered, choil is well polished. By engraving his name Naohito on to the knivves, you can tell that he must be really proud of his work, and I trust you will enjoy his knife as well.

That they are not as they appear in photos.
The photos do not show that there is a section for the big toe and the rest is open. The photo shows as if the whole toe section is one opening instead of two. They work for what I want but just not what I thought they would be.

Not as pictured
The pictures make it seem like these are open all the way across. There are actually two holes. It is quite tight on the big toe. I will keep these, however I would not order these again.

Comfortable toeless socks
Very soft and comfortable. However, the elastic is too tight. Should be wider so circulation is not cut and you are able to wear it at night. Therefore, is not good for diabetic and heavier people. Larger sizes should be available.
