To complete its competence in metallising and heat treatment, Deguy-Conge has a metallurgical laboratory equipped with the means for carrying out sectioning, coating, polishing and microscopic observations. With modern design and fabrication tools, we meet the most diverse technical requirements. Our long experience enables us to define the steel and heat treatments that are adapted to the conditions under which the knife is used. Equipped with modern technologies, we apply tungsten carbide coatings to knives with the most diverse shapes. Bevels therefore withstand wearing and this considerably increases their lifespan.
