Balancing both comfort and sharpness, Derby Double-Edge Safety Razor Blades have been made using some of the most modern manufacturing technologies available. Despite this, Derby razor blades remain compatible with all traditional safety razors, ranging from Merkur to Weishi. Their cutting edges have been coated using ceramic, chromium, platinum, and tungsten, deposited there using a process called sputtering. Combined, these materials help protect the cutting edges from rust while also increasing their hardness for better retention of sharpness. Derby razor blades must undergo rigorous inspections at each stage of their manufacture to pass muster. Once those inspections are complete, each one is packaged using wax paper to keep out moisture before being put into the sealed containers. 
Azmusebat is the Turkish manufacturer that sells its razor blades under the Derby name. Possessing state-of-the-art facilities, Azmusebat is able to maintain a strong position in the Turkish market for both lighters and safety razor blades.
