Ask Aaron Q/A: Top tips on extending the life of double edge razor blades
John Bennett, from the UK, asks:
“Aaron, I have a Merkur safety razor and also a shavette, both with disposable blades. (This is to avoid having to attempt to sharpen a straight razor). When using disposable blades how many shaves should you get per blade? And any tips on how to get the best from them? I usually use the Derby blades.”
AARON SAYS
“Mr. Bennett,
Thanks for your question! Unfortunately the answer is quite subjective. There are many variables on how many shaves a blades lasts and it also depends from person to person.
The best way to know when your blade needs changing is when it begins to pull the hair instead of cut it smoothly. Whatever that point is, whether it be two days or ten, is the time to change blades.
If you want to extend your blade life, swish your razor in rubbing/isopropanol alcohol or take a cotton swab that has been soaked in oil and run it along the blade edge.
This removes the water from the blade edge causing less corrosion leading to a dull blade edge. Try these tips and you’ll see an increase in your blade life!
There is also the option to invest in a razor blade sharpener like the RazorPit.
Smooth Shaving!

Ask Aaron Q&A: Turning razor blades around at periodic intervals
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.”
AARON SAYS
“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!
Aaron”
