The unmistakable hallmark of the JANUS collection is the black blade - symbol of the highest quality and functionality thanks to the finishing with the high-quality DLC technology (Diamond-Like-Carbon). As a special coating for the highest stress, it optimizes the functional properties of the blade. The carbon layer, which is only a few micrometers thick, is insensitive to acids, bases and extreme temperatures and is characterized by low friction values and enormous scratch resistance.
