Refurbishing of OEM Tool steel knives: The Smart choice
After some time in operation, industrial knives become damaged—most commonly through chipping of the cutting edge. At first glance, there seems to be only one solution: purchasing new knives. Real-world experience shows there is a second, both economically and technically advantageous option—knife regeneration.
Why Consider Regeneration?
OEM tool steel knives are designed for high performance and durability. Their lifespan, however, does not have to end with the first sign of damage. Thanks to modern technologies, these knives can be repeatedly restored without losing their functionality.
Regeneration offers several key benefits:
- Cost savings – regeneration costs approximately 50–70% of a new knife
- Maintained performance – regenerated knives perform the same as new ones
- Long-term solution – the process can be repeated up to 10 times
This means that instead of repeatedly investing in new parts, customers can effectively plan their costs while maintaining smooth production operations.
How Does Knife Regeneration Work?
Knife regeneration is not just a simple repair. It is a precise technological process that restores the original properties of the knife.
In brief, the process includes:
- Removal of the hardened layer
The worn or damaged part is removed to prepare the base for new material. - Welding with a flexible layer
A base layer is applied to ensure strong bonding. - Hardfacing (60 HRC)
A special high-hardness material is applied to form a new cutting edge. - Pre-grinding to required dimensions
The knife is shaped to approximate size. - Additional weld adjustment
Final refinement of the welded material. - Final grinding with precision ± 0.05 mm
Achieving high accuracy and quality comparable to a new knife.

Reliable Results You Can Count On
A properly regenerated knife:
- achieves the same performance as a new one
- handles the same workload
- maintains precise dimensions and a high-quality cutting edge
When the process is carried out correctly, there is no loss in quality or efficiency.
Conclusion: An Investment That Makes Sense
If your OEM knives become chipped, it doesn’t automatically mean high costs for new parts. Regeneration offers a reliable alternative that:
- reduces costs
- maintains performance
- extends tool lifespan
With proper planning, you can significantly optimize operational expenses without compromising on quality.
