Designing OneBlade: The Active Floating Blade System 

The Active Floating Blade System (AFBS) in a OneBlade razor provides users with an extra level of forgiveness in their shave. This slight rattling or vibration of the blade is by design. The creators of the razor might have stumbled upon this notion by accident, but today all OneBlade razors are crafted to an extremely narrow tolerance that specifically allows the slightest possible movement of the blade inside the razor head.
