Shaving Replacements: Razor Blades & Trimmer Heads
A dull razor blade is the primary cause of razor burn, ingrown hairs, and skin irritation. Each shave microscopically damages the blade edge, and after 5-7 uses, the blade tears rather than cuts hair. Compatible cartridges use the same stainless steel or titanium-coated blades as brand-name razors at a fraction of the cost.

Razor cartridge compatibility follows the handle platform. Gillette Fusion, ProGlide, and Fusion5 cartridges are cross-compatible. Schick Hydro 3 and 5 cartridges fit their respective handles. Compatible cartridges are engineered to match the blade geometry, lubricating strip composition, and pivot mechanism of the OEM design.
For electric shavers and trimmers, replacement heads are model-specific. Philips Norelco rotary heads are classified by number series (SH30, SH50, SH70, SH90). Braun foil shavers use cassette-style heads numbered by series (32B, 32S, 52B). Always match the series number, not just the shaver model name.
Blade quality is measured by the coating. Entry-level blades use stainless steel. Mid-range blades add chromium coating for corrosion resistance. Premium blades use titanium or diamond-like carbon (DLC) coating for the sharpest, longest-lasting edge. Compatible cartridges at the premium tier use the same coating technology as OEM.
