Matsubara HAP40 Bunka 180mm is made by blacksmith Katsuto Tanaka who works from his famed shop in Omura City, Nagasaki Prefecture.
HAP40 is considered a top-shelf steel that is semi-stainless and holds an edge incredibly well. The core steel is covered in san-mai style with soft stainless steel. The cladding adds strength, reduces mass, and makes maintenance a lot easier.
This great-looking bunka has a rather flat section at the heel end and then transitions into a nice curved belly about halfway along the edge.
