3-Blade System: The Mach3 razor is built around a three-blade shaving surface. The blades are progressively positioned to cut hair closer with each pass, which is designed to provide a close and smooth shave.

Lubrication Strip: Each cartridge includes a lubrication strip at the top. This strip releases lubricants to help the blade glide smoothly over the skin and reduce irritation. The strip's color fades over time, acting as a visual cue that it's time to replace the blade.

Microfin Skin Guard: The blades are preceded by a series of soft microfins. These fins gently stretch the skin to create a smooth surface, helping the blades to cut the hair more effectively and comfortably.

Durability: According to Gillette, the Mach3 blades are stronger than steel and are engineered to last for up to 15 comfortable shaves.

Compatibility: The Mach3 blades are cross-compatible, meaning a single Mach3 blade refill can be used with any Gillette Mach3, Mach3 Turbo, or Mach3 Sensitive handle. This allows for flexibility and makes it easy to replace a single blade when needed.
