Eight American-Made Blades

Regular price $6
Supply warranty, free shipping and 100 day free trial

Half a dozen blades in your razor: it sounds great in a marketing pamphlet, but in practice it leads to irritation, redness, and ingrown hairs. At the same time, fiddling with standard single blades by hand isn't exactly appealing, either.

Enter the Single Edge injector blades – eight sturdy stubble-slicers packed into a custom-built cartridge. The simple mechanism lets you reload your Single Edge razor with a satisfying click, avoiding all contact between your fingers and the blade.

8 Injector Blades (90-Day Supply)

United States of America

Stainless Steel

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, American-made injector blades. A pack of blades typically lasts up to six months and only cost $0.75 per blade to replace.

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!

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.

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.

One Cartridge, Three Months of Shaving

You're getting a lot of firepower in one little package. Eight blades will keep you fresh-faced for an entire summer (or winter, or rainy season). It's all recyclable, and there's a blade disposal slot in the back so you never need to fill your trash with sharp objects.

Wesley E Morris
Best ever

These are the best blades that I have used in quite some time. I have been shaving for over 60 years. The Supply razor is fantastic when combined with your blades. I don’t have to worry about nicking myself. I’m now on blood thinners and was supposed to stop using a blade razor. I am not a fan of electric razors so I started the search for a good, safe razor. I have tried the big name razors but I was able to nick myself with all of them, until I found Supply. I have not had any issues since using your product!

Thank you so much for the 5-star review Wesley! Please don't hesitate to let us know if there is ever anything we can do for you!

I am a believer for sure!

Received my razor yesterday and used it today for the first time. It did take me a few minutes to get used to the handle and shaving angle, but after those few moments, I had completed my shave and yes, it was close and comfortable. I have been a "5 blader" for years with the "Big G" company but now, for the cost and effectiveness, you have me. The advertising and marketing for the Source razor is very buttoned up but I am always skeptical about the relationship between promotion and true product performance. You guys did not mislead for even one moment. I really appreciate that.

Thank you so much for the 5-star review Steven -- I really appreciate it! Please don't hesitate to let us know if there is ever anything we can do for you!
