Sakai Takayuki Aoniko Blue 2 Steel
The blade of "AONIKO" line is uniquely "ALL" made of famous Yasugi Aoko or Blue Paper (Aogami) No.2 Steel in monosteel construction (solid piece of Blue Paper No.2).
The material is known as prime high carbon steel, specifically developed for tools and knives, and has highest wear resistance and toughness because of special hardness.
If you already have some experience with stainless Japanese kitchen knife, such as Misono UX10 or Sakai Takayuki Grand Chef, and wanted to go a step further to really try out the "real Japanese edge", the Aoniko line is probably one of the best options out there.
The handles on these knives are hand crafted out of Mahogany wood, which is water resistant and beautifully grained.
