Our handmade Yoshihiro Hongasumi knives are crafted with extraordinary skill by our master artisans to create high quality knives that are indispensable in their craftsmanship and performance. Blue Steel #2 with a hardness on the Rockwell scale of 63 to 64, is forged with iron to create beautiful mist patterns, and an empahsis is placed on refined forging and polishing with the highest attention to detail. This knife is part of a limited edition that has the Japanese laquering technique of Fuki Urushi on its Japanese style handcrafted Magnolia wood handle affixed with a Water Buffalo horn bolster, and a Fuki Urushi laquered Magnolia wood protective sheath called a Saya with indentations called Chinagashi that are usually seen on Samurai sword sheaths. The Deba knife is a heavy knife that was made to filet and butcher whole fish. The heft of the Deba knife allows it to cut through the heads and bones of a fish, and its smaller pointed tip filets the flesh from the bones. The Deba knife can used be for chicken and meat but is not recommended for cutting through large bones. The Deba knife is one of the most essential of traditional Japanese knives and is a powerful component in the repertoire of many chefs. Even the simplest of tasks are elevated with a handcrafted knife that is as beautiful as it is functional.
