Knife sharpening
Do you work with paper cutting knives, granulating knives, veneer knives, or shear knives? Then you regularly have to deal with wear and tear caused by the production process. For 85+ years, De Rooy Grinding Centre has been turning every blunt knife back into a valuable tool.

Knife sharpening service
Your production process depends on good, functioning tools. A blunt knife can really get in the way. With our extensive range of machinery, we can sharpen blades for any industry. Fast, reliable and accurate. This ensures that your production process continues to run optimally.
Delivery of new knives
At some point, your knife will reach the end of its useful life. Even then, De Rooy Grinding Centre helps keep your production process going. We are happy to provide you with a new knife, in any desired quality and according to your exact specifications. In addition, we can also supply various accessories, such as cutting blades for the graphics industry.
Pick-up and delivery service
We have our own transport service, which we use to collect blunt knives and return them sharpened and in perfect condition. We do this for our customers, visiting them on a weekly basis. In case of emergency, please call us. We will ensure that your knife is collected and returned sharpened as quickly as possible.
