Hongasumi Hassouchi Gyokuseiko Knives

Our hand crafted stock is extremely limited. Purchase now to avoid any delays!



The Hassouchi knife is produced by combining four layers of Ao-ko high-carbon steel with four layers of soft iron. United by an additional forge-welding and hammering process, the metals are perfectly balanced and create beautiful wavy patterns throughout  the blade. The resultant knife has a sharpness that is comparable to the highest quality Honyaki knives, while it excels in both strength and sharpening ease. The combination also gives the knife and excellent durability of sharpness and a strong nick-resistance.
