Improved service life and sharpness without compromising the sharpening process: Cryogenic hardening is a technically complex process in which the steel is cooled to -150 °C under computer control after hardening. After this treatment, the steel contains finer carbides that cannot form during the normal hardening process. This results in outstanding properties such as longer service life than with conventional hardening, fine cutting edge formation with low burr formation and easier sharpening.
