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.

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.

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!

Dynamite blades

Great long lasting blades and no fuss replacement. No fumbling with the blades just inject and move on. Nice little spot to slide the old ones into too.

Bruce Johnson
Superior Blades

Nearly a year since purchasing my supply razor (all stainless). The supply blades are the perfect compliment to a high quality instrument. I’d give them 6 stars if I could. I’ve tried Shick blades and they are fine. The supply blade is just better!

Great blades, close shave.

These give me a very close and smooth shave. The only downside is they dull after about one shave. However, if image this is the same with most straight razors. I'm never going back to those disposable plastic razors!

Hey Jason! We're so thrilled to have you as a customer with us but no so thrilled to hear that you aren't getting the most out of your blades. I have a couple of ideas as to what might be going on and would love to help if you're interested. Just shoot us a quick email at I'd love to help!

Joshua Jackson
Precision and Smooth

I get an amazing shave! The blades cut the hair with precision and my face is very smooth afterward. My sideburns come out perfect and level with the precision of the blade. No razor bumps, no issues. Once you get the hang of how to shave with this single blade, you will love it!

Love to hear it Joshua! So glad to hear you are enjoying the precision of our blades. Thanks for being part of the Supply family!
