Inexpensive Derby Black Premium blades are made of stainless steel rolled steel and are standard size. They can be used to refill a classic safety razor or shavette razor. One plate is enough to shave without irritation at least 4—5 times.
The composite coating of the cutting edge extends its service life. It consists of:
- Chromium — prevents edge pitting and the appearance of rust islands;
- ceramics — literally fuses all layers of the composite coating into a single unit;
- platinum — increases the sharpness of the sharpening and its precision;
- Tungsten — enhances durability and reduces friction.
Derby Extra is another popular line of the brand’s blades, specially designed for men with sensitive skin and medium-hard stubble. Compared to them, the hardness of Black Premium is higher, as the series in black packages was created for shaving stiff and very stiff stubble. In our store you can buy an economical pack of Derby Black Premium, 100 pcs.
