About Togiharu Togiharu is Korin’s house brand and was created with the user in mind. The Togiharu brand was created for functionality and is Korin’s most affordable brand of knives. The brand name was derived from Grand Master sharpener Shouzou Mizuyama’s father’s sharpening store. Master Mizuyama’s father was a celebrated sharpener in his own right, having received recognition from the emperor for his traditional sharpening skills. Togiharu knives are produced by a highly respected knife maker in Japan who manufactures the top-name Japanese brands. The difference in the Togiharu lines lies in the quality control and hand-finishing aspects of production. These knives are inspected one-by-one for quality - they are not mass handled. The final edge finishing process is done by hand, ensuring unparalleled sharpness right out of the box.
