Single Edge Blades

Regular price $6

Pack Size

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!

Blade review

With a bit of care and using the two-dot setting, I can reliably obtain a one-pass BBS shave. If I do a two-pass shave my face feels like it has never grown hair. It's hard to beat that.

Hey Robert! Love to hear you are enjoying those BBS with our Single Edge. It is hard to beat a shave where you only feel your skin!

Great blades for a great razor!

I have been a customer of the Supply razor and single edge blades for the past year and I love the product. These blades are sharp, strong, and give a great shave! They are easy to change on your razor, with the genius insert-push blade cartridge. I have also noticed a lot less or no more razor bumps on my skin after shaving. This was a big problem for me with my previous razors. I would definitely recommend this razor/blade to anyone looking to try something new after having no luck with all the other razors in the market!

Hey Lionel! Love to see you've been enjoying your Single Edge for the last year. We love having customers like yourself and I'm so thrilled to see you've been experiencing fewer and fewer razor bumps!

Thumbs up

Hey Bill! Love to read that - two thumbs up on my end. Thrilled to see you are enjoying our Single Edge blades. Let us know if there is ever anything we can do for you!

So far, so good

Have only used my Supply razor twice. A lot easier to switch from cartridge razor than I thought. Still learning all the nuances but I’m getting there. I’ll never go back to cartridge razors.

Hey Chet! Love to hear you are getting used to our Single Edge and that you won't be going back to those cartridge razors. It takes about a week or so to get used to the handle so take your time and enjoy the shave!

Great product!

I’ve been using this shaving set for around 9 months now and my face is loving it! Better skin complexion with less breakouts and ingrown beard hairs. It’s a little pricey to get started, but inexpensive to reorder new blades and continue on with the product/company. Definitely recommend to anyone in the market for a new shaving experience. 1 blade razors > multi-blade razors.

Hey Kyle! Love to hear you've been enjoying your Single Edge Blades and that you've been experiencing fewer breakouts and ingrown hairs. Let us know if there is ever anything we can do for you!
