The striking new collection by the brand Masakage and blacksmith Yoshimi Kato is called Yuki - snow. The subtle whiteness of the blade and the light magnolia handle are designed to remind one of a snowy winter landscape. With a carbon steel core and stainless outer layers, this line represents the perfect blend of beauty and performance.

The shape of the Ko-Bunka makes it a multi-purpose knife, similar to the Santoku, and very easy to use. The word Bunka in Japanese means culture, and Ko small. The 135mm Yuki Ko-Bunka is a kind of cross between a Petty, Nakiri, and Mini Santoku knife. It has a characteristic Bunka shape with a pronounced tip reminiscent of Tanto blades. The knife will prove to be a great, versatile Utility knife ideal for chopping herbs, preparing vegetables, and even cutting smaller pieces of meat. With its versatile profile and original look, Yuki Ko-Bunka will become the star of your kitchen arsenal.

The finish of the blade is called Nashiji, the literal translation of the word being "the skin of an (Asian) pear". It refers to the slightly matted surface of the upper part of the blade, which not only has aesthetic value but is also practical, since the uneven surface reduces the sticking of the food to the blade when slicing.  

The knife’s core is Shirogami 2 (White 2) steel, surrounded by two layers of stainless steel that also hugs the spine of the blade. The knife is hardened to 62-63 HRC. The combination of carbon steel core and stainless outer layers gives us the best of both worlds: easy maintenance and rust protection on one hand and sharpness, a silky smooth edge and efficient cutting and chopping on the other. Using the blade will give it a patina on the lower edge of the blade along the shinogi line separating the layers of steel. Despite the rust-proof outer layers, the knife must be cleaned with regular and careful wiping and occasional application of Ballistol oil is recommended.

Yoshimi Kato, a relatively young blacksmith from the famous Takefu village, known for many skilled blacksmiths, gave the blade a traditional japanese handle, oval in shape, made of magnolia wood with a ring made of red (stabilized) wood.

The knife is packed in a beautiful box - the natural blue colored paper has silver coloured kanji - signature by the master blacksmith. The box comes with a gift coin and a certificate stamped by the blacksmith and sharpener.
