Let me see…how to describe this knife. Design similar to some found in German cutlery sets, made by a Japanese knife company, using Swedish steel. IMHO, that is a great combination. Razor sharp right out of the box. Excellent for small work. I will get the 150mm when they are back in stock. Note the only point still outstanding is I have not used enough to fully assess the edge retention. At this point I have no concerns that it won’t be as good as other common quality stainless steels used for kitchen cutlery.
