Matsubara knives are crafted by Katsuto Tanaka,  a fourth-generation blacksmith working in Omura City, on the island of Kyushu, a region with a history of knife crafting that dates back hundreds of years. 

This line features hammer-forged blades made from a white #1 steel core for excellent edge retention and clad with a softer steel in the san mai style for stain-resistance and ease of sharpening and maintenance.  The knives are fitted with beautiful walnut handles.

Due to the unique shape of each knife, wooden sheaths do not fit Matsubara knives.
