This Matsubara 175mm Bunka has a thin, reverse-tanto style tip that is liked by many knife aficionados. These blades are often called Hakatas in the south near Nagasaki on the island of Kyushu, where this knife style is part of any good home Japanese kitchen.
The blade is made from Aogami 2 steel, which is hardened to a Rockwell rating of 62HRC. This is a perfect level for Blue #2. It is then clad with a layer of soft stainless steel using the san-mai method of laminating a blade. This involves covering both sides of the blade without wrapping the outer layer (jigane) over the spine. The hagane thus shows through at the edge and on top of the spine. These knives must be kept clean and dry to avoid corrosion to the exposed hagane. The jigane is treated to a really well executed nashiji, or pear skin, finish.
This fun and functional blade is mated to an equally fun custom handle. It really is a great match!
