Masamoto Ao-ko Hongasumi

正本 本霞 • 玉青鋼誂

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.


  • HRc: 62-63 
  • Bevel: Single Edged 
  • Steel Type: Blue Steel #2 (Moisture and acidity will cause discoloration or rust)

For Left-Handed Customer

  • Left-handed blades must be special ordered from Japan, and will cost 50% more than the right-handed blades. Due to how each traditional Japanese knife is handmade by right handed craftsmen, it will take 4 to 6 weeks to forge and deliver.
