Setup, Compatibility & Care
To install, simply unscrew or open the head of your double-edge safety razor, carefully place the Derby Extra blade onto the alignment pins, and secure the cap. Ensure the blade is centered before tightening.
Regarding care, always rinse your razor thoroughly after each shave to remove soap and hair debris. Do not wipe the edge of the blade, as this can dull the multi-coat finish. Store your razor in a dry area to maximize the lifespan of the stainless steel core. When the blade begins to tug or feel 'dull'—typically after 3 to 5 shaves—replace it to maintain an irritation-free experience. Always dispose of used blades in a designated blade bank or sharps container.
