The Single Edge SE and Pro are injector-style razors. The injector packs may look like something new, but they’ve actually been in production for over 100 years.
The first one was invented by Lt. Colonel Jacob Schick. He made the injector pack to operate like the magazine for a semiautomatic rifle.
But how do you use this unique, but oh-so-satisfying injector pack? Here's a quick video for the visual learners and step-by-step instructions below, if needed.
Step #1: Know When It’s Time
No one wants to shave with a dull blade. One of the best ways to know it’s time to swap them out is if you notice the blade is tugging your hair. Or if you start dealing with some post shave irritation, it’s time for a new one.
You’ll get better and better at recognizing when it’s time to change blades over time.
Step #2: Load The “Key” Into Your Razor
Our blade pack has a key that fits into the right side of the razor head. Make sure you push the key all the way into the opening of the razor head, otherwise you won’t be able to properly load a new blade.
The new blade will push the old blade out, so if the pack isn’t loaded correctly, your pack may lock up.
Step #3: Pull The Slide Back
There is a slide on top of the injector pack that will catch the new blade and then push it into place in your razor.
Step #4: Push The Slide Forward
Now, push the slide forward. This will load a new blade in the razor while simultaneously ejecting the old blade on the other side.
Step #5: Safely Store The Old Blade
There's a neat little opening on the back of our blade packs. You can slide your old blade into the back of the pack while you're still using the other blades in there. Then, once you’re finished with all 8 blades in your pack, toss the whole thing in the recycling bin.
