Service

We manufacture to drawing, customer sample or original Pierret reference. We hold knives in stock and offer a fast spares and replacement service, plus regrinding of technical knives, to guarantee the continuity of your production.

Common questions

For which Pierret models do you make knives?

For the most common models (CT60N, N45, N60, P26, R45, S50) and to drawing for others, in special steels or tungsten carbide.

What do Pierret knives cut?

Synthetic fibres, technical tapes and special materials, with geometries that minimise friction and high thermal stability in extrusion.

Why does the knife’s thermal behaviour matter?

When cutting fibres and polymers, friction generates heat. If the steel loses hardness with temperature, the edge rounds off quickly, so we use steels and treatments that retain it.

Can you manufacture from the original Pierret reference?

Yes. We work from the OEM reference, the technical drawing or a physical sample of the knife to be replaced.
