The well-rounded knife steel

Alleima® 12C27 is our most well-rounded knife steel with excellent edge performance allowing razor sharpness, high hardness, exceptional toughness and good corrosion resistance.

Alleima® 12C27™ is our main knife steel for hand-held knives, high-end ice skate blades and ice drills. Continuous improvement over a period of 45 years has evolved it into the high performing steel grade it is today. The composition is tighter, the purity level is much higher and the fine carbide microstructure of today is far from how our Alleima® 12C27™ knife steel of the sixties looked.

With a hardness range of 54-61 HRC, high toughness, scary sharpness and good corrosion resistance, Alleima® 12C27™ is the recommended grade for hunting knives, pocket knives, camping knives, high-end chef's knives and tactical knives.

Like most of our knife steels this grade is fineblankable enabling efficient production.
