The blades are made from Japanese steel and feature an automatic grinding mechanism. As you use the shaver, the blades are continuously sharpened, maintaining their sharpness and durability over time.

7.3 Blade Replacement
While the blades are designed for long-term sharpness, they may eventually require replacement. Replacement cutter heads can be purchased separately. Refer to the product's official website or authorized retailers for compatible replacement parts.
