Knife Care

HAP40 has a chromium content of less than 5% and is considered semi-stainless. The Akashide stainless steel cladding means most of the blade is easy to care for. The knife edge below the cladding line will form a natural grey patina over time. But if you leave it to drip dry it will rust. Rust can be easily removed with rust cleaner or a rust eraser. 

There's no need to oil the knife if its cleaned and dried properly. If you prefer an even lower maintenance knife, look for a full stainless steel blade. But if advanced edge retention is high on your priority list, the Akashide HAP40 knives are definately well worth considering.

Hachido Knives

Hachido – Eight Paths in Japanese, has a root of the Ancient Buddhist concept of the Noble Eightfold path. In terms of Hachido knives it refers to The Steel, The Quench, The Sharpening, The Polish, The Fit, The Finish, The Feel and The Cut. To be called a Hachido knife the knife must excel in these 8 paths.

Care Instructions

Knife care for semi-stainless steel knives

The core is made of semi-stainless steel which is MORE rust and tarnish resistant than carbon steel, but LESS rust and tarnish resistant than stainless steel. The most important knife care tip is to keep your knife dry and do not leave wet overnight.

  • Never put in the dishwasher.
  • Dry thoroughly after handwashing and do not store unless fully dry.
  • The knife is not quite stainless so is susceptible to rust if left wet overnight.
  • A grey patina might form after a time, this will not harm the knife in any way.
  • Do not cut through bones, frozen foods or extremely dense items.
  • Always cut with a smooth action and never twist the blade, sideways pressure will damage the blade.
  • Use Japanese waterstones to sharpen your knife.
  • We recommend rust cleaner for maintenance.
