In the Steel workshop

Two types of steel are worked:

L’acier carbone

Our carbon steel is extremely hard, thereby ensuring that the cutting edge is maintained, little wear and easy regrinding.
The carbon is not very corrosion-resistant: we advise you to avoid damp environments and to wipe and oil the blade after use.

Stainless steel

Our stainless steel is Swedish – 12C27 modified (Sandvik). The addition of chrome makes it highly corrosion-resistant. Its carbon content of at least equal to 0.40% gives it an excellent cutting edge.

The blade

Cut out from a strip of steel, the blade is heat-treated to alter the internal structure of the steel, making it very hard. This raw blade then passes through a series of specific grinding wheels in the fully robotised grinding-polishing machines. They give it the unique domed Opinel profile which ensures unrivalled strength and cutting edge.

The Virobloc

Invented by Marcel Opinel in 1955, the Virobloc safety ring was improved on all Opinel ranges in 2000. In addition to the blade in the open position (safety in use), the blade can now be locked in the closed position (safety in transport). The virobloc has two parts: a fixed part and a sliding part. It is cut out of stainless steel and then shaped.
