Nitrided blades are high-carbon, hardened steel blades that surpass the quality and durability of most standard blades on trimmers. Nitrided Blades are FoodSafe; the materials used are approved for contact with food products.

The diffusion of these elements gives the metal enhanced mechanical properties compared with untreated steel. The process involves pre-heating the untreated steel material which is then placed in a liquid salt bath where the nitrogen and carbon are diffused into the surface of the material. The part is then quenched in another liquid bath for black oxide treatment and finally rinsed and cleaned. The resulting part benefits from an aesthetic black colour as well as some of the enhanced properties listed above.
