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!

Black label blades and face scrub

The face scrub is by far my favorite, and the feeling it leaves on your face is relaxing. I brought it over to my gf’s and safe to say I’m not getting it back now. The black label blades are nice, but if I’m being completely honest I don’t really notice much of a difference between those and the white label with my shave. Nonetheless, great blades and company. Thank you!

Great razor, great blades

Best razor that is out there right now.

Gary Krieger
Love these new blades

First time I could shave my head with no nicks but must also use the se razor

Chirag Desai
Simple mechanism for blade replacement

Apart from the fact the blades are cheap and good. I think the sold out is the replacement mechanism; which helps accident free replacement and collection for the old blades.

Ian Fletcher

Best shave I’ve ever had!

My new go to blade

I finally caved and gave the black label a try. Glad I did

Harris Masterson
So far so good

I recently replaced my single blades and found that these blades are much more sharp then the original Supply single blades. I also like the black container and the fact that they are Japanese. I’m noticing a bit more irritation then usual, but I think this is due to my changing to a completely different type of blade

Trinidad Torres
Love the new blades

The older blades worked wonderfully and somehow they improved the shave. It feels more smooth and less irritation. Excellent product.
