Using Magnets to maintain blade sharpness has been a known science as long back as Circa 1930 when The ‘Vintage Monroe Magnetic Blade sharpener’ was sold across the United States. The Mag T Delta Razor uses this science, creating a self sharpening mechanism with the help of 2 powerful Neodymium rare earth magnets. Aligned with the blades edge they create a strong magnetic flux preventing ionic loss of material from the edge, maintaining a sharper blade for longer.
