Where do I buy blades for The Single Edge?

The Single Edge accepts "injector" style blades, which can be purchased easily on our website. Visit this link to learn more.

Injector blades are non-proprietary to Supply - they were first invented by Col Jacob Schick in the early 1900s. They can be purchased at a number of online retailers. (But ours are the best 😉)

Who makes your blades?

Our blades are proudly made in the United States by a razor manufacturing company that has been producing blades for over 100 years.

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.

What's the difference between double edge (DE) blades and injector 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. 

No flex means no blade chatter, which is a common issue with both multi-blade and single blade razors - causing irritation, nicks, and cuts. Most users get anywhere from 8 to 10 shaves out of our blades.

How do I load blades in your razor?

With The Single Edge, blade changes are lightning fast, dead simple, and touch free. Every razor ships with a magazine of 8 blades that is used to inject a new blade into the razor handle - and eject the old blade. Once the package is empty, it can be dropped in the recycle bin - and a new pack can be purchased for just $6.

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!

How do I change my shave setting? Do I need a new blade?

We are currently working on a video to show how to easily swap out your settings while using the same blade. It is easy to do and take advantage of the customizable options of the Single Edge razor.

First, hold the head of your razor between your thumb and your index finger in your non-dominant hand. Using your dominant hand, loosen the screw and uninstall the existing shave setting, while holding the blade in place with your non-dominant hand. Then, grab your new setting, install in your razor, and tighten the screw to complete the swap. The blade should be flushed against the blade stops, and the screw should be hand tightened.

Remember to never insert a new blade into an empty razor head!

If you would like to use new blade with your new setting, either follow the steps above, and then inject a new blade as you normally would. Or, you can manually insert a new blade by taking your razor apart, disposing of the old blade, and placing a new blade on the setting of your choice, flushed against the blade stops. Then, screw in the setting while holding the blade in place with your thumb and index finger on either side of the setting.

Does the Single Edge accept "Artist Club" style blades?

Artist Club Blades are slightly larger than injector blades, and will not fit in the Single Edge. The Single Edge takes standard injector blades, which can be easily purchased on our website.
