Manufacturer bounces back from mid-life crisis to take on the globe

Pete Nicholson C4 Carbides

This is a story of glittering diamonds, an entrepreneur resting on his laurels and blades that can cut through steel quicker than you can say Mack the Knife, writes Mathilde Murphy, Trade & Information Team Manager at Enterprise Europe Network.

Around a decade ago, Peter Nicholson’s company C4 Carbides, a Cambridge-based blade manufacturer, had cracked America and was chugging along nicely with a turnover of £3m a year. But the industry was moving fast and Peter had a simple choice: innovate or stagnate.

“When I set up the company many years ago, I was very creative and imaginative,” explains the C4 Carbides founder and CEO. “But when people start to think a lot of themselves they stop looking outside the box. Innovation started to scare me.”

A meeting with John Christopher from the Enterprise Europe Network in 2009 reignited Peter’s entrepreneurial streak, tapped into grants that led to ground-breaking R&D, patents and products, and helped treble his turnover.

A key introduction was to the University of Hertfordshire, enabling Peter to inject academic rigour into his engineering team: “You’re forced into making certain that your project really is new rather than something already invented 20 years ago in Germany.”

The result was a revolutionary hard metal blade, coated in diamonds, creating a cutting edge with unprecedented resilience.

“John helped to reignite the company, introducing me to grants and inviting me to various functions. Without that I don’t think the company would be revived.”

C4 Carbides is now a truly international business selling its revolutionary blades to the United States, Japan, China, Switzerland and across Europe. Nicholson is now working on his next big breakthrough: 3D printing of ‘smart teeth’ made from functionally graded super abrasive materials. And with this market estimated to be worth £2.5bn globally, he plans to grow his company’s turnover from £11m today to £70m over the next decade.
