Stop Settling For Cartridge Razors That Weren't Made For Maturing Skin.

As skin matures, it becomes thinner, more sensitive, and slower to heal—which means the nicks, redness, and razor burn from cartridge blades don't just sting, they stick around longer.


The truth is, cartridge razors were never designed with your skin in mind, they were designed for profit. Multiple blades mean multiple passes over already-sensitive skin, and that constant friction is exactly what's causing the redness, irritation, and slow-healing nicks you've been putting up with.

You may have heard other men your age talking about switching to a safety razor, and they're onto something. The SL-1 uses a single, precision blade with a protective guard that glides cleanly with far less pressure — meaning your skin gets the close shave it needs without the punishment it doesn't.

Tough On Thick Beards

If you've been battling your thick beard with a cartridge razor, dealing with clogged blades, tugging, multiple passes that still leave patches, and a drawer full of expensive refills then the SL-1 Safety Razor was built for exactly this problem.

A single, sharp blade cuts cleanly through even the densest stubble in one smooth stroke, instead of the dragging and pulling you get when five dull blades try to do the job together.

The SL-1's weighted handle gives you effortless control, letting the razor do the work so you're not pressing down and irritating your skin. No more razor burn from blades that have given up by Wednesday. Just a close, clean shave every time — whether you're trimming a neckline or taking down a full thick beard from scratch.

Easy To Use

  • Put In a Sharp Blade

    Twist to open SL-1 and put in a sharp blade. Twist again to shut and the head will hold the blade secure at a safe angle.

  • Lather It Up

    Add water directly to your shave soap and vigorously mix to create a protective nourishing lather. Our shave soap is unscented and perfect for sensitive skin.

  • Apply Soap With Brush

    Use your shave brush to generously apply a protective layer of lather to your neck and face. The soft brush helps exfoliate your skin as you apply the lather.

  • Light Pressure

    Use quick short strokes when shaving. The key is to let the heavy weight and sharp blade cut through your hair, just simply guide it. Rinse frequently.

    No Guesswork. Just A Steady, Confident Shave.

    Unlike a straight razor our dads would use, a safety razor features a protective guard positioned just behind the blade edge, controlling the angle and exposure so the blade glides across your skin without nicking or cutting.

    Simply put, our razor takes the guesswork out of what angle to shave at.

    More Frequently Asked Questions

    How often should I change the blade?


    For the most comfortable, irritation-free experience, we recommend changing the blade every 1-2 shaves.

    I have extremely sensitive skin. Is this right for me?


    The SL-1 was designed specifically for you. By reducing the number of blades from five to one, you reduce the friction on your skin. This preserves your skin’s natural moisture barrier and prevents the razor burn associated with traditional cartridges.



    I have really thick hair. Will this still work for me?

    Absolutely. The weighted solid metal design of the SL-1 is ideal for thick hair because it provides the stability and cutting power needed to slice through thick stubble effortlessly.




    Does the SL-1 use proprietary blades?

    No, the SL-1 uses standard double edged safety razors you can buy anywhere.

    If You Think It's Expensive...

    Customers Say It Better

    • I can’t be bothered shaving everyday, so it is every other day, or sometimes every three days. This razor with the right blades makes shaving a lot easier even with my thick regrowth.

    • I prefer to shave upward, since it results in a nicer, smoother finish. Been doing that for about 2 years, and with some caution and aftercare, I rarely ever experience cuts or irritation.

    • I now get the hype. Shaving is smooth, my skin gets really smooth and there's no friction when shaving. No signs of irritation. Skin is smooth like a baby's butt.
