The Masamoto Ao-ko Layered Hongasumi knives are crafted by uniting four layers of blue carbon steel #2 and soft iron steel. The beautiful pattern on the blades is crafted by a combination of special forge welding and hammering processes. The layers of blue steel create a longer edge retention and more chip-resistant blade than white carbon steel hongasumi knives.
