5-Blade Technology: Fusion cartridges are known for having five anti-friction blades that are spaced closely together. This design helps to distribute shaving pressure evenly across the blades, which can lead to a more comfortable shave and less irritation.

Precision Trimmer: On the back of the cartridge, there is a single blade. This precision trimmer is ideal for shaving tricky areas like under the nose and for shaping sideburns or facial hair.

Lubrication Strip: A "Lubrastrip" on the top of the blades releases water-soluble lubricants to help the razor glide smoothly over the skin. The strip fades to white over time, indicating that it's time for a new blade.
