We created MRMK to be different from other machine knives manufacturers.

Sharper for Longer

Engineered to deliver powerful cutting performance. InfinitEdge is the ultimate choice for smooth, uninterrupted production.

Our Factory

By owning our Sheffield factory, we are able to guarantee quality by owning the entire process, from grinding high-grade steel to directly delivering your products to anywhere in the world. That means we can continually innovate to make your machine knives even better.

Creating a new standard

By taking your products and ideas, using drawings or samples from production to packaging, we are always working to the highest standards in machine blade manufacturing, whilst using cost-effective methods to ensure you always get the best possible prices.

We’re able to break the decades-long cycle of big manufacturers creating complex processes and overcharging and do things the MRMK way–focused on high quality, fair prices and customer satisfaction that you deserve.

Precision Blades, Expertly Engineered

Our knives are manufactured from hardened stainless steel which has been sourced from only ISO 9001:2008 accredited suppliers. Whatever your requirements are, we can help. At MRMK we genuinely care; offering peace of mind, reliable parts, fully finished products and a real solution to your machine knife needs – that’s why we are the industrial blade supplier of choice for many of the UK’s leading brands.
