Alongside machinery, PetroLuc supplies industrial cutting knives and blades for recycling and plastic processing equipment. These knives are engineered for shredders, granulators, and mills used in plastic, rubber, wood, film, and RDF processing, and are trusted by machine operators across Europe and worldwide.

Every knife we supply is manufactured from high-alloy tool steel, selected specifically for cutting performance, wear resistance, and long service life under continuous mechanical stress. The choice of steel, and the precise combination of alloying elements within it, is what separates a knife that holds its edge under heavy industrial use from one that wears out prematurely. We offer knives across a range of steel grades and hardness levels, so the specification can be matched to the material being processed and the demands of the machine it runs in.

Precision Manufacturing

Our knives are produced using modern mechanical and thermal processing equipment, supported by dedicated in-house design and development expertise. This allows every blade to be manufactured to tight dimensional tolerances and put through carefully controlled heat treatment, ensuring consistent hardness, durability, and cutting quality batch after batch. Beyond standard tool steels, we can also source specialist, higher-performance steel grades from leading European steel manufacturers for applications that demand it.

Trusted Across the Industry

Our knives are fitted into recycling and processing machinery used by manufacturers and operators across the plastic, rubber, wood, film, and RDF sectors, and are relied upon in demanding industrial environments worldwide. Whether you are running an existing machine and need a like-for-like replacement blade, or specifying knives for a new installation, we can match the right steel grade and specification to your process.
