Blade length : 8.5 cmBlade material Sandvik stainless steel: the modified Sandvik 12C27 stainless steel developed for Opinel is renowned for its sharpness and ease of maintenance. Stainless steel capable of undergoing the heat treatment that gives it its good hardness is called martensitic. It has a carbon content of at least 0.40%, which gives it a very satisfactory cutting edge without being susceptible to corrosionYatagan blade: the traditional Opinel blade is known as the Yatagan blade. Its shape is inspired by a Turkish sword, with a raised tip. The blade is ground to an exclusive curved profile, guaranteeing its robustness and allowing high-performance sharpeningHandle: the hornbeam comes from French farms. It's a white wood with little grain, ideal for decolouring. The handle is varnished for better protection against moisture and dirtSafety ring: Invented in 1955 by Marcel Opinel, the Virobloc safety ring is fitted to all closing knives from N°06 upwards. Cut from stainless steel, the Virobloc consists of two parts: a fixed part and a sliding part. In addition to locking the blade in the open position (for safe use), it is now possible to lock the blade in the closed position (for safe transport).
