This is their 180mm nashiji ginsanko bunka. Ginsanko or Hitachi Silver#3 is our favorite stainless steel. It sharpens like a carbon and becomes scary sharp like a carbon; it's a joy to use. (Carbon steel has a reputation of being able to be sharpened very easily and has a higher peak sharpness compared to stainless; this is why veteran knife enthusiasts love carbon steel in general or carbon-like stainless steels like Ginsanko).
We have tested sharpening our demo knife and it's definitely one of the easiest stainless steel to sharpen. It can get scary sharp, too, even with just a quick session on a medium stone. This is on par with our reference knife, a Kagekiyo ginsanko santoku (Kagekiyo is one of the premium brands in Sakai).
