Swedish 12C27 modified Sandvik stainless steel IS used in the construction of this knife. The addition of chrome means it is extremely anti-corrosive and requires no special maintenance. It has an excellent cutting edge thanks to its 0.40% carbon content.
Opinel blades are all ground to a convex profile – the blade can be ground efficiently and maintains its robustness. To avoid causing harm to the environment (via transport pollution, deforestation etc), 95% of wooden handles come from French logging.
