Knives / Blades
Discover robust MetavCUT block knives and related cutting tools designed for efficient recycling. Our range includes hollow‑ground knives, shredding and scraper blades engineered for long service life and reliable throughput. Optimised materials balance wear resistance and fracture safety for varied input conditions.
Durable Knives / Blades for Efficient Recycling Operations
Knives / Blades are essential components in recycling and shredding systems, designed to process a wide range of materials with precision and reliability. This category covers Block Knives, Hollow-Groove Knives (Hohlkehlenmesser) and other cutting solutions that increase throughput, extend uptime and reduce unplanned downtime. The right selection of Knives directly influences wear behaviour, breakage risk and long-term operating costs.
How the Right Block Knives Boost Plant Performance
Designed for high-throughput applications, Block Knives slice, shear and crush input material so downstream processes run smoothly. Material selection and heat treatment determine hardness and toughness: Chrom-Vanadium Steel variants offer significantly longer Stand Time but require cleaner input to avoid fracture, while lower-hardened steels tolerate contaminants better at the expense of service life. Precision manufacturing ensures consistent cut geometry and predictable wear patterns, resulting in fewer interruptions and easier maintenance planning.
When Shape and Material Decide the Outcome
In many plants the choice between a straight Block Knife and a Hollow-Groove Knife alters material flow and chip removal. Hollow-Groove Knives feature a concave middle that helps guide shredded pieces and can reduce clogging in specific feeds. In mixed-waste or scrap-heavy inputs, selecting a less brittle alloy lowers the risk of catastrophic breakage caused by foreign bodies. Practical considerations such as mounting type, reversible edges and fit to existing shafts are critical for rapid replacement and safe operation.
Why MetavCUT Is a Strong Partner for Recycling Needs
MetavCUT supplies precision-fit, economical spare parts engineered for recycling machinery. Their portfolio includes Block Knives, Hollow-Groove Knives, Cutting Knives, scraping blades and specialized tools tailored to shredders and shears. Products are described as passgenaue Eigenmarken (precision-fit own-brand components) rather than OEM originals, offering reliable compatibility and straightforward replacement. For technical inquiries, the manufacturer’s product range and support can help optimise tool life and process efficiency.

FAQ
Are MetavCUT block knives suitable for all types of shredding machines?
MetavCUT block knives are designed as robust, precision cutting tools for recycling and shredding applications. They come in various shapes and material hardnesses to suit different feed materials and machine requirements. High-hardness chrome‑vanadium steel variants offer longer life for clean inputs but can be more brittle when foreign objects are present; lower‑hardened versions are less prone to breakage from contaminants but have shorter wear life. Choose the variant matched to your machine and material mix for best results.
How do I choose between a block knife and a hollow‑ground (concave) knife for my recycling line?
Block knives provide strong, stable cutting performance for general shredding tasks, while hollow‑ground (concave) knives feature an inward‑curving profile with higher outer edges and a recessed centre, which can improve cutting characteristics for specific materials. Consider the material type, desired throughput and tolerance for contamination: hollow‑ground knives can offer different cutting geometries that may be beneficial for particular feeds.
Can MetavCUT knives be used as direct replacements for original equipment manufacturer parts?
MetavCUT supplies precisely fitting replacement and wear parts as an own brand; they are not original manufacturer parts but are engineered to match common dimensions and performance needs. Verify compatibility with your machine specifications before ordering.
What maintenance practices extend the life of recycling knives and blades?
Regular inspection for wear, timely regrinding or replacement, correct mounting and alignment, and avoiding excessive contamination in the feed material will maximise uptime. Keeping a stock of critical spare knives reduces downtime during planned maintenance.
Do you offer custom sizes or special steels for specific applications?
Yes, MetavCUT offers a range of knife variants and materials; consult the product range to find options like different hardness levels and geometries, or contact the supplier for bespoke solutions.
How quickly can I get replacements delivered for production‑critical machines?
Delivery times depend on stock availability and order location. For urgent production needs, contact the supplier to confirm current lead times and express shipping options.
