The Science of Single-Blade Shaving (2025)

The angle of the blade determines whether or not you are cutting the hair off your face or scraping it off. We opted not to leave this to chance and spent months testing just how much surface area was appropriate and the ratio of height and width that would allow the user to ensure razor head was properly oriented on their face without relying on pain as the indicator.

This meant that we needed the flat surfaces above and below the blade aperture to be just the right size and proportioned and oriented in just the right way. This also meant that the two surfaces needed to be almost on the same plane, but not exactly. In order to create just the right amount of friction and suction during shaving we had to be careful not to have too much surface area in contact with the skin to avoid a ‘stick slip’ experience wherein the razor head would tend to suction onto the soapy wet skin during the shaving process. So while the angle of any razor plays a big role in performance and comfort, OneBlade has removed almost all of the guess work.

Everything starts with the raw material. The Hitachi-made high carbon stainless steel starts with the finest and most consistent carbon grain of any raw material available. With the very best steel available, Feather, using proprietary processes, grinds, hones, and strops the sharpest and smoothest edge in the marketplace. As the worldwide leader in blade manufacturing for the medical industry, there is no competitor that can meet their rigorous performance standards.

OneBlade, sharing Feather's dedication for excellence and performance, recognized the perfection that is the Feather FHS-10 blade and build our razors to work in concert with the finest cutting edge available.
