Zafirro is the sharpest razor around

We’ve had three- and four-blade razors, so what’s next? This is.

It’s called Zafirro, and it claims to be “the biggest advance in razor blade technology in more than a half century”. Its blades are made of sapphire, which is second only to diamond in terms of innate hardness. As such, its blades should stay sharp for six to 12 months, according to the makers. Though they claim that soon they’ll be able to increase this to “several years”.

It’s so sharp, in fact, that the people behind Zafirro claim it’s more than 10 times sharper than a surgeon’s scalpel. This is because it’s only 80 atoms at the tip, which is about 5,000 times narrower than the width of a human hair.

Of course you will still need to replace them. The replacements will cost less than $49 (£32), though the firm can’t say exactly how much yet.

The firm launched its first Zafirro razor in 2011, and it cost $100,000. A year later it launched the Zafirro Gold, which comparatively was much more affordable, at just $18,000. It’s selling the new model – the Zafirro Z2 – for $149, though those are all gone. If you’re quick, you can get one for $179 (£118). So far, it’s raised over $50,000 of a $250,000 goal, with 49 days to go.

It’s not the first razor to hit Kickstarter. The Skarp laser razor was kicked off the crowdfunding site after the firm couldn’t provide a working prototype. Until we can shave with lasers, the Zafirro will do us just fine.
