The Ulm-based company has been manufacturing blades coated with synthetic diamonds for almost a decade, albeit for less-glamourous equipment such as medical scalpels, drill bits, and probe needles. That was before Andre Flöter, founder of GFD, had the brainwave to apply diamond’s near-invulnerability to break into the multibillion-dollar consumer razor industry.
GFD engineers use a “plasma-sharpening” process to create a cutting edge as small as 3 nanometers.
But toughness isn’t the only quality the hirsute look for in razors. To ensure a clean, close shave, GFD engineers use a “plasma-sharpening” process that involves sticking dozens of blades upright in a vacuum chamber and then pummeling them with oxygen or chlorine gas that has been excited to a plasma state. The resulting radius of curvature at the cutting edge, according to GFD, can be as small as 3 nanometers—or only a few atoms in width.
Of course, blades manufactured this way would cost a lot more than conventional ones, but Flöter insists that they’ll pay for themselves in the long term. “If one adds together the costs of disposable razors over the period of one year,” he says, “then our diamond blade could certainly be a reasonably priced alternative.”Did you like this post?
