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!

Great Blades for a Great Shave!

The Black Label Blades were a step up form the original which were great in their own right. The Black Label Blades gave an even smoother shave and are longer lasting. I may be new to Supply, but have been wet shaving with single blade and dual blade shavers for about 30 years. The combination of the razor, shave cream and the Black Label Blades have given me some of the smoothest and irritation free shaves I've ever had. Thanks for a great product line!

John Hart
Smooth and sharp!

I quite like the new black label blades. They are smooth and sharp in equal measure. Perhaps not as sharp as the Schicks out of China, but much smoother for me. YMMV, but for me these are a great match with my Supply razor or any injector.

Hey John! Love to hear you are enjoying the new Black Label Blades and that they are offering you that smooth shave. Let us know if there is ever anything we can do for you!

James Fennelly
Even better than the original blades.

The upgrade in quality from the original blades is subtle but noticeable. A great product that doesn’t cost a fortune!

Hey James! Love to hear you are enjoying the new Black label blades. Let us know if there is ever anything we can do for you!

Love my supply razor!!!

I used to shave only rarely, a few times a month… with regular 5 blade razors I’d get cuts, razor burn, or just an uncomfortable shave, not to mention the cost of replacement blades!!! With my single edge from supply I shave regularly, multiple times a week! The blades, in particular the new black labels, are phenomenal!!! They last through many shaves and maintain a great sharp edge for a clean, close, comfortable shave. Thank you Supply, I'm glad I found you!

Black Label Blades

The Black Label Blades are immensely better than your original blades, that were great to begin with!!

Supply has made something that is already amazing, better.

Long story short, the Single Edge Razor paired with these new Black Label Blades produce the best shaving experience I've ever had. Prior to using these Black Label Blades, I used the original blades that came with my Single Edge Razor and that experience was and has been the best I've ever had.

I am one of the guys - probably a lot like me who now use this razor - that have tried way too many razors that we care to admit; especially to my wife. Every single time I would try a new razor with 3 blades, 4 blades, or 6 blades the experience would be the same:
1. The hype and excitement phase: basically telling my self that this brand new razor is the one! It feels great and looks so cool.
2. Ignoring the fact that once I got to shaving my neck, the tugging and burning feeling became present.
3. After using it maybe 3 times, the regret sinks in and I start looking for another razor.

I can honestly say that after using the Single Edge Razor the first time, I had the same reaction noted in the 1st bullet above. But #2 and #3 never happened. Each subsequent shave session became better as I got more used to using it. Each shave session became faster. And most importantly, each shave session ended without any tugging, pulling, cuts, burning, irritation, or anything like that.

The razor it self is a simple piece of metal beautifully machined. The blade is a normal looking shaving blade. The magic sauce is how these two pieces work together. The right angle of the blade, the weight of the handle, the pure simplicity of everything just works. Every time.

I can't recommend this razor enough. I'm telling you right now - if you are on the fence about this razor, just buy it. The 100 day trial is WAY more than enough time you will need to know you'll just be keeping it and use it literally forever.

Blades of glory

The new blades are much better and glide right through the hair. I’ll be using these from now on. Happy that Supply invested in different blades.

William Mollock
Great blades

The newer white label blades in the 8 pack actually worked very well for me. But these are even nicer. Sharper and clean cutting, with a bit more blade feel, not overly aggressive though.

Black Label Blades work great

I stopped using the Supply razor because I could not find any blades that worked for me. The black label blades are working great. Smooth shave no cuts or nicks.

Hey Rick! I'm so glad to hear you are enjoying the new Black Label Blades and that you are now able to enjoy a smooth, comfortable shave. Let us know if there is ever anything we can do for you!

Jack Southall
