The manufacturing process

Our knives and cutting tools are produced in a four-step process. Each stage is important to ensure a high-quality end product and we guarantee maximum care and accuracy throughout. The most important steps in the process are cutting, hardening and coating.



We cut the material you want to use. We can use a laser-cutting process with a continuous or pulsed laser beam that can cut all types of material using ablation technology. We also have the option of a water-jet cutting process. We use both techniques to cut complex two-dimensional or three-dimensional outlines quickly, precisely and efficiently.


We increase the stability and resilience of your tools using a variety of hardening processes. Conversion hardening, precipitation hardening or strain hardening ensure the maximum robustness and the longer life of your tool.


We coat your tools. Our physical vapour deposition (PVD) process provides a hard coating. We can also apply a non-stick coating to your tools. As well as preventing adhesion and reducing the cleaning, these coatings also notably increase the life of your tool. Extending service life is our top priority when it comes to new products and regrinding.


Hard coatings in PVD process

Hard coatings in TiN, TiALN, CrN, DLC in our PVD process on all tools up to 1,200 mm maximum length for:

– Increasing the service life
– Cutting edge rounding
– Reducing the surface roughness depth
– Reducing the friction coefficients


Non-stick coating

Non-stick coatings in various mixture qualities on the surfaces of numerous tools for:

– Corrosion protection
– Food integrity
– Food protection
– Preventing product adhesion build-up
– Preventing unwanted product coatings
– Reducing roughness depth
– Reducing friction coefficients

Our machines

We would be nothing without our machines. And our machines would be nothing without us. To talk about a love affair might be putting it too strongly. But it wouldn’t be totally wrong. Some of the machines that live in our pool date from the days when the “Miracle of Bern” was celebrated and rock ‘n’ roll was all the rage. These heirlooms from the post-war period need particular care and specialist know-how; but they can do things that other machines can’t. Our latest machine was purchased in 2018 and we have built many of the machines ourselves. This combination of old and new means that we are best equipped to deal with any requests.
