8 perfectly crafted blades come in our QuickLoadTM cartridge. You’ll get that tactical reload feeling every time you load a new blade.

Includes 8 Injector Blades (90-Day Supply)

Origin Japan

Material High-Carbon Stainless Steel

Coating Chromium + PTFE

Dimensions 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 , Amazon.com, 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!
Supply press mentions

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.

TWICE AS THICK
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.

Pro Razor Mirror polish and Black Label blades

All I can say is “SUPERBLY DONE”!!

I was so impressed by how wonderful I found my shaved with this razor and blade combination that I bought the same setup (including the case) for my brother who is also a wet shaving enthusiast.

I am also adding to my collection the SE RAZOR in both Rose gold and yellow gold finished.

Thanks for your exceptional products.

Thank you so much for the 5-star review John -- I really appreciate it! If ever there is anything we can do for you, just let us know!

Great but expensive

Super sharp and easy to install. Shipping from the USA makes them very expensive. When will these blades be available in the UK?

Thank you so much Warren for giving a 5-star review! Please let us know if there's anything else we can do for you!

Wonderful

I am satisfied so far with the blades that I have used.
There was one that was dull and would not cut
Just replaced it with another and it was good.

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

Sharp and Long Lasting

I had a problem with my first pack of blades, where the sliding mechanism wouldn’t grab the blade for insertion. The team from Supply did not hesitate to make the issue right. I wear a beard and therefore only shave my neck and cheek area. I get at least 4-6 weeks out of a blade shaving 3 days a week. I have zero complaints about the blade or the quality of the shave.

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

great experience

Never tried this type of shaver before so didn't know what to expect. I am really impressed and love it. And it is so much more environmentally friendly with very little plastic except the multi blade carrier. Huge fan of less packaging in our world. Shave is great. Product does everything advertised and really has the feel of a high quality product. Highly recommend.

Thank you so much for the 5-star review, John! Happy to know that you are having a great experience with our products! If ever there is anything we can do for you, just let us know!
