Razor blades must be chosen for the shaving system they are designed to fit. The collection includes double-edge blades from different manufacturers, single-edge formats, HeadBlade cartridges and a blade bank for storing used blades safely.

Confirm compatibility before comparing sharpness or price. Double-edge blades can feel different in the same razor because the edge, coating and individual technique all affect the shave; a small pack is useful when testing a new blade. Replace a blade when it begins to tug, requires extra pressure or no longer gives an even result. Head-shaving cartridges and single-edge blades are not interchangeable with standard double-edge blades. Place used loose blades in a suitable blade bank.
