The Derby Professional single edge razor blades are designed specifically for use in barber razors and cut throat shavers. Each blade is crafted from high-quality stainless steel sourced from Sweden or Japan, ensuring a reliable and sharp edge for precise grooming. To enhance performance and longevity, the steel is treated with a combination of chromium-ceramic, tungsten, and platinum coatings. A final polymer layer is applied to the surface to provide a smoother glide across the skin, which helps reduce irritation during the shave. These blades come in a pack of 100, with each one individually wrapped in wax paper to maintain hygiene and protect the edge from moisture. This makes them a practical choice for professional barbers or home users who prefer the traditional feel of a straight razor.
