Ask Aaron Q&A: Turning razor blades around at periodic intervals

ask aaron image

Gary Whittles, from the UK, asks:

“I enjoy double edge razor shaving, preferring the Israeli blades to the Derby blades. However, I have noticed that the Derby blades have numbers 1 and 2 o one side with 3 and 4 on the other. What is the significance of these numbers and should I be turning my blades around at periodic intervals.”


“Mr. Whittles,
I too have seen those numbers and wondered what they were there for. After doing some reading and exploring I eventually found that they have only to do with the manufacturing side of the process. Turning or flipping your blade does not increase it’s lifespan (although some will swear it does) or maintain its sharpness. Thanks very much for your question!

Smooth shaving!
