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!

Best shave EVER!

This product changed my skin! Shaving my head with multiple blades razors made the ingrown hair issue atrocious with inevitable scars! Since switching to supply, NO ingrown hairs and every product I have used is unsurpassed in quality. The absolute best!

Best razor ever

I have used the multi blade razors by both the name brand and discount brand. I even tried to use a safety razor( got a lot of cuts from that one). I use the razor for both my face and head. This razor gives a great shave on both areas. Best investment by far. I am even going to buy a second one to keep in my travel bag!

Solid Build Quality

Unlike brand-name razor blades, these blades feel sturdy and cut effortlessly through my stubble!

Great shaving experience

Love the experience from lathering up, using the badger brush, the marble bowl, actually shaving and the after shave! Bought the chrome razor stand after the initial purchase. The razor stand is the best touch!

I’m enjoying shaving, can you believe that?

I’m still ‘new’ to wet shaving with a single edge razor. I’ve spent the past month using the Comfortable setting and just moved on to the Ultra Close.

I didn’t think I could get a closer shave but Ultra really did the trick! I got as close and complete a shave in one stroke as I did with Comfort and 2 to 3 strokes!

I like the shave cream, it makes wonderful lather, and especially the Post Shave spray! My skin feels great after an application without any ‘burn’ we’re all familiar with from alcohol after shaves.

I continue to tell my friends about Supply.

Last a very long time. I can't go back to my $600 electric or my safety razer.

I normally don't review products but this is an exception for an exceptional product and all-star service. I have had my Supply razor over a year now and am constantly amazed at the quality construction and weight of the razor. I have tried a ton of different razors over the years. Multiple blades double edge injectors you name it. I have come to the conclusion that this razor is a precision grooming tool in every aspect. I have a really tough beard with sensitive skin and I get the next best thing to a good barber shave. As for the blades I had a few of my old injector blades that did fit my supply razor but no comparison, I threw them away. I usually put in a new blade on Monday nights and could probably push it beyond that, but 7 quality shaves is a bargain indeed. I have the marble bowl razor stand and travel case all top shelf products to say the least. I have not yet tried their other grooming supplies but plan on do so in the near future.
Thank you Supply family for your dedication to quality and customer needs.
