Invented by Marcel Opinel in 1955, the Virobloc safety ring is fitted to all folding knives from the N° 06. Cut out of stainless steel, the Virobloc has two sections, one fixed and one sliding. In addition to locking the blade open (safety in use), it is now possible to lock the blade closed (safety in transport).
