Zirconia ceramic cutting blades

Zirconia ceramic cutting blades are rightly considered to be the top in cutting. Their extreme high hardness offers a high blade endurance and defines the FORTIUS ZR series (orange safety box).

However this property comes with a compromise: an increased risk of breakage due to inherent higher brittleness. In other words, the blades are fragile.


A breaking razorblade during the slitting process is to be avoided at all cost:

    • You do not want to take the risk that zirconia particles end up in your customer's end products. 
    • Small blade fragments that turn in the web make the film unusable (e.g. film for food packaging).
    • Zirconia ceramic particles are not metal detectable. The risk small zirconia cutting parts end up by the end user, is important.
    • A potential extrusion or converting line stop is a considerable cost.


The solution lies in the choice for blades with more resilience like Fortis or Fortis +. Their concept: a resilient stainless steel body combined with a ceramic coated cutting edge, which:

    • offers high cutting performance, and 
    • most importantly eliminates the danger of breakage.
