Zafirro claims to have the world’s sharpest razor. Their latest blade is made of Sapphire which is one of the toughest material on the planet. Thats why the Zafirro razor has 10x sharpness than regular blades available and its tip is about 80 atoms; that is 5000 times smaller then human hair. Because they are expensive to create it took four years to Zafirro to create an affordable razor with sapphire blade at this price. And they claim that their sharp razors can handle for 3-5 years of usage. Available on Kickstarter you can get the Sapphire Blade Razor for as low as $199.
