B30 Butterfly Double Edge Razor Safety Razor All razor blades
These razors are not designed to be bullied into the beard or skin. In fact, doing such will undoubtedly lead to bleeding or irritation. Instead, double edges should gently glide across the face, and even with light pressure, will adeptly remove stubborn stubble.
Double edge razors should move across the beard area at an angle of approximately 30 degrees. Shaving should commence slowly and carefully with short, light strokes in the direction of hair growth. Since hair grows in different directions on every man, make sure to take note of your specific hair direction prior to shaving. That said, obviously no slicing or side-to-side motion.
More so than with multi-blade cartridges, double edge razors do their best work on skin that is held taut. So, when taking passes on the cheeks or neck, use that free hand to stretch these areas.
