Detailed Description
The Funayuki is a traditional Japanese knife that is used by fisherman aboard their boats indeed, Funayuki literally translates in to English as "going on boat". These knives are often used by fishermen to clean, fillet and quality test small or medium-sized fish. However, in the past, fishermen also used their Funayuki to prepare food for themselves (either out at sea, or back at port), so the knife also had to be capable of cutting meat, vegetables and fruit - just like the similarly versatile Santoku and Gyuto.

You might think that the blade shape of the Funayuki appears similar to a Deba or Mioroshi Deba, however, the blade of the Funayuki is much lighter, thinner and more agile; Consequently, it should not be used to cut through bones, frozen food, or other hard ingredients. Because the Funayuki has a relatively flat blade profile, it works particularly well with 'push-cuts' and 'pull-cuts', however, it can also be used in a rocking motion to mince herbs or other ingredients. Not surprisingly, the Funayuki excels at filleting small fish, but it is also quite suitable for breaking down poultry.

Aogami Super (Hitachi Metals Ltd.) is one of the greatest Japanese carbon steels. In addition to containing more carbon, chromium and tungsten than Blue Steel No 1.
It has very good edge sharpness and excellent edge retention, but is also capable of attaining high hardness without being brittle.Consequently, many knife enthusiasts rate Aogami Super as one of the very best high carbon steels in the world.
