This knife series is the result of a close collaboration between Hatsukokoro and one of the most renowned knife manufacturers in Seki City, Japan. We are immensely impressed by this knife series, which delivers not only a beautiful finish but also consistently thin and refined edges of outstanding quality. 
The blade is crafted from high-performance VG-10 stainless steel, encased by two layers of softer steel that have been hammer-finished and mirror-polished. The mirror finish fades into a hazy "kireha" that contrasts nicely with the polished core steel. The octagonal handle is made of ebony, adding to the knife's luxurious aesthetic. We highly recommend this knife!
