Also known as DE Blades, safety razor blades or single Edge Blades, when it comes to double edge blades, our advice is to try as many different types as you can. All double edge blades are of a standard shape that will fit any safety razor, but differ in their sharpness and coating, making for a different shave experience every time. The only way to know if a blade is going to work for you is to try it for yourself. If you’re unsure, pick up a Double Edge Blade Sample Pack, which allows you to test run the range, from the mild Merkur blade to the samurai-sharp Japanese Feather blade. For effective and safe used blade disposal, consider a Blade Bank.
