The Masamoto Ao-ko Hongasumi blades are crafted from a combination of blue carbon steel #2 and soft iron steel. Blue steel #2 is created by mixing chromium and tungsten with white carbon steel in order to produce a blade with longer edge retention than white carbon steel blades. The forging process includes several extra steps and requires a higher level of craftsmanship than kasumi style knives, which gives hongasumi knives a more refined finish.
