Precision replacement counter knives and stripper combs for optimised shredding performance
Precision replacement counter knives and stripper combs ensure clean, efficient material reduction by forming the opposing cutting surface to the rotor, enabling optimal shearing when correctly angled; they are engineered for recycling shredders to improve throughput and reduce downtime by offering variants such as counter knives, stripper combs and wear‑hardened designs that suit abrasive, contaminant‑rich materials and balance a hard exterior with a tough core for impact resistance.
improve shred quality and uptime with counter blades and stripper combs
Metav supplies precision counter blades and stripper combs tailored to a wide range of industrial shredders. Treated here as two complementary components — counter blades (also referred to as counter knives) and stripper combs (also known as scraper combs) — they form the opposing cutting partners to the rotor-mounted cutting crowns and determine final particle quality.
how they work and where they matter most
counter blades and stripper combs form the mechanical counterpart to the cutting crown; the cutting action depends on the correct angle to the rotor and precise contact geometry. Optimised shapes and choice of material reduce wear and maintain cutting performance. in recycling and shredding lines, especially when processing mixed or contaminant-rich feedstock, case-hardened designs combine a hardened outer layer with a tougher core to resist chipping while absorbing impact.
measurable benefits that affect your bottom line
- increased stand time through optimised geometry and material selection
- improved cut quality and throughput with correct angle to the rotor
- reduced unplanned downtime thanks to case-hardened variants for contaminant-rich materials
- easier maintenance and predictable wear patterns for fast replacement and shorter r&r times
- compatibility across many machine lines for simplified stocking and reduced part complexity

FAQ
What is the difference between counter blades and stripper combs?
Counter blades act as the opposing cutting surface to the rotor-mounted cutting crown, while stripper combs support material flow and remove debris between cutting elements. both items are essential for consistent shred quality.
How does the angle to the rotor affect cutting performance?
The angle to the rotor determines the relative contact and shear between cutting crown and counter blade; correctly set angles ensure efficient cutting, lower forces and more even wear on counter blades and stripper combs.
When should I specify case-hardened counter blades?
Choose case-hardened counter blades when processing contaminant-rich or abrasive materials; the hardened surface improves resistance to chipping while a tougher core reduces the risk of catastrophic fracture.
Can Metav provide parts for my specific shredder brand?
Metav supplies counter blades and stripper combs compatible with many established shredder manufacturers and will advise on the correct variant to match your machine and application.
