The Korin Shiro-ko Hongasumi knives are forged in Japan from a combination of white carbon steel #2 and soft iron steel, then handled with magnolia wood and a water buffalo bolster. White steel’s pure carbon content allows for the sharpest cutting edge. The main difference between the kasumi and hongasumi line is found in the crafting process. More steps, higher level craftsmen, and greater attention to detail are involved when crafting hongasumi knives, therefore are more refined than kasumi knives.
Drawing from a tradition of Japanese craftsmanship and meticulous attention to detail, the collections at Korin showcase exceptional sharpness and time-tested durability. We are dedicated to bringing the highest quality Japanese knives to your kitchen, so you can experience the unparalleled quality of Japanese craftsmanship in your home or restaurant.
Purpose of Usuba
The usuba is a traditional Japanese style knife designed to cut vegetables. Japanese cuisine stresses the importance and beauty of seasonal ingredients, referred to as `shun.’ The literal translation of usuba is `thin blade.’ Without this incredibly sharp and thin blade, the knife would break down the cell walls of vegetables, causing ingredients to discolor and decrease in flavor. Originated in Kanto (Tokyo) region.
