It has long been understood that by subjecting metal tools to elevated temperatures

close-parting5a22f249223abskew-close5a22f233d0102and then rapidly cooling them, the properties of the metal can be altered. This happens because the crystal structure of the metal is altered to change the way the metal reacts when in use. 

The two main crystals in tooling steel are the larger and softer austenite and the smaller, more stable martensite. Through heat treatment, we look to transform the austenite to martensite to produce steel with good wear
characteristics and an amount of
ductile properties. 

When combined with a good quality heat treatment, the cryogenic process greatly enhances the austenitic transformation. Also at these extreme temperature of -301ºF (-185ºC), fine ‘eta’ carbides are formed within the carbon structure. Growing very slowly and only at these very low temperatures, ‘eta' carbides are extremely small and act as a ‘filler’ between the other crystals in the metal. 

The combined effect of the cryogenic processing is to produce a refined crystal structure in your hand tool that will give a lifetime's service by producing a blade that will retain its edge longer and give a superior ‘feel’ in use.
