The Matsubara White #1 bunka
is fashioned from Hitachi White Paper #1 steel, also known as Shirogami 1. The inner core, or hagane, is clad in a soft carbon jigane (outer layer). The outer layer features a rustic and attractive kurouchi finish. Kurouchi is a black carbonized finish put on knives to protect the steel and provide a barrier against corrosion on carbon steel knives. It also adds strength to the inner core. However as this is a carbon blade, care must be taken to clean and dry it after use.
Bunkas, or banno-bunkas, can be viewed as a cross between a gyuto
and a nakiri
. They are similar in overall dimension to a santoku
, but with that distinctive Edo-style sword tip. They are versatile and nimble knives capable of tackling all sorts of cutting, chopping, and slicing jobs around the kitchen. Bunkas feature a flatter profile than many other gyuto blades and are particularly suited to push cutting techniques rather than rocking styles. The attractive and great looking sword tip makes it very useful for small or intricate work like preparing garnishes.
The knife comes with a simple but good looking octagonal rosewood handle and black pakka wood ferrule.
