What type of blades are these?
The Single Edge accepts standard "injector" style blades. Each razor ships with a magazine of 8 stainless steel, Japanese-made injector blades. A pack of blades typically lasts up to three months and only cost roughly 10 cents per shave.

Are they proprietary?
Nope! These blades have been in production for 100 years and can be easily purchased on our website , Amazon.com, and more.

How long do they last?
Everybody changes out their blades at different intervals due to the fact that our skin, hair, and preferences are all different. That said, most customers easily get 8 to 10 shaves out of each blade. A single pack of eight blades can last up to three months if you shave 5-6 times a week.

How are these blades different from DE blades?
Our blades are twice as thick as blades that are used in both multi-blade and single blade razors, which means they flex less, they cut cleaner, and they last longer. Fun fact: injector blades were originally invented by Schick in the early 1900’s. They quickly developed a cult following as a safer alternative to the Gillette double edge blades.

How do I dispose of used razor blades? Do they create waste?
Each Single Edge ships with a magazine of 8 stainless steel injector razor blades. If you look at the back of the pack, you will see a nifty opening to insert used blades. No sharp objects lying in your trash can or recycling bin unattended or waiting for an unsuspecting toddler or pet to find. Once you are through with all of your blades, you can recycle the entire magazine, blades and all. Safe and better for the environment!

  1. Insert the key from your blade pack into the head of the Single Edge Razor.
  2. Push the slider across - toward the razor - to inject a blade.
  3. You just swapped out your blade in less than 2 seconds without touching the actual blade!
Supply press mentions
Pair of hands reloading the supply Black label blades
safe & easy
Butterfingers? No Problem

All other single-blade razors force you to unwrap and load thin, sharp blades by hand. That's why we designed a custom-built injector mechanism which keeps your fingers safe, and enables lightning-fast blade changes.

TWICE AS THICK
No Cutting Corners – Only Hairs

Unlike some of our competitors, we refuse to scrimp on materials. Single Edge blades are twice as thick as standard razor blades, meaning that each one stays sharp for longer.

Awesome

So far so good. There’s a learning curve, but I’m getting it. The price for the quality and quantity was big for me. The first few shaves with a new blade erases the hair away with how smooth it is.

Thank you so much Arturo for giving a 5-star review to the Black Label Blades -- appreciate it! Let us know if there is ever anything we can do for you!
