8 Injector Blades (90-Day Supply)


High-Carbon Stainless Steel

Chromium + PTFE

Length: 38.1 mm (1.5")
Cutting Edge Length: 36.3mm (1.43")
Width: 8 mm (.314")
Thickness: .25 mm (.025")

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 ,, 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!

Exceptional Blades

Supply Black Label blades give a very comfortable shave and last through 8 shades. I have a very thick course beard.

Richard Bright

I must admit I wondered if I would notice the difference between the black label blades and the white label ones I’ve been using for the past 18 months. I do! They are really sharp and smooth and, paired with the SE, give a marvellous shave. Very highly recommended.

Just when I thought it couldn’t get any better

I went and got the Black Label Blades and, boy, was I wrong. These things are LEGIT! Such a smooth shave, way less irritation. And I was happy with the White Blades too, these things are excellent though. I don’t anticipate using a different blade. For ever.
Listen to me … Get! These! Blades!

No more knicks. Very smooth shave. Made shaving fun again.

Harold Burke

Using the new black label blades has been a very pleasant experience. The best way to describe it is smooth as silk no nicks or cuts. Ingrown hairs are almost nonexistent.

Great Customer support

I got the black blades after the Supply team reached out asking if I’d like to try them. Customer support was super kind and helpful and gave me a great experience!
