About Our Services

  • We heat-treat most grades of steels, including Carbon, Stainless & Damascus, up to a maximum length of 900mm (36″).
  • We cannot heat treat High-Speed Steels.
  • Heat treatment is usually performed every Wednesday, with dispatch by the last post on Friday.

Our Process

  • With digitally controlled hardening furnaces, we ensure precise and consistent results for every blade.
  • Our unique hybrid quenching system, combining an industrially formulated mineral quench oil and a quench press, virtually eliminates blade distortion.
  • We utilize anti-scaling paints and stainless foil to safeguard against decarburization and scaling, eliminating the need for sandblast cleaning post-heat treatment.

Additional Services

  • Tang toughening service for hidden tang blades (highly recommended).
  • Hamon service for plain high carbon steel blades (1080, 1095, 26C3, etc.). Sketch your desired hamon pattern on the back of the info sheet.
  • For laminated steels (San Mai, Takefu Multilayer, Cu Mai, Ni Mai, etc.), we have developed special hardening techniques to reduce the likelihood of centre line cracking of the core.
  • Tempering is tailored to suit each blade’s material and requirements with further distortion correcting measures being applied if necessary.

Cryogenic Treatment and Hardness Testing

  • While we do not have liquid nitrogen or dry ice cryogenic facilities, our oil quenching process followed by cooling to -32 Celsius for a minimum of one hour yields excellent results for stainless steel blades.
  • All blades undergo hardness testing on the tang, with a test certificate provided. Please note that certain steels and clad materials may not be testable due to their soft outer layers.
