Why Switch

The multi-blade cartridge is the problem.

Five blades dragging across your skin is the reason for the burn, the bumps, and the ingrowns – and you're paying a premium for the privilege.

The Single Edge SE + Year of Blades - Shaving

01. The cartridge tax

Brand-name cartridges run $3–$5 each. A single edge blade costs about $1. Ours are twice as thick as standard razor blades and made in Seki City, Japan.

02. Multi-blade irritation

02. Multi-blade irritation

Each pass tugs and lifts the hair before cutting it. More blades means more drag, more redness, more ingrown hairs.

03. Plastic you throw away

Disposable heads pile up in a landfill. One solid-metal razor, guaranteed for life, replaces all of it.

THE TANK, 2019

One blade. On national TV.

We walked into Shark Tank with fake mustaches and a comedian dressed as George Washington. Patrick's mustache fell off mid-pitch. Lori called it "the Cadillac of razors." The Sharks fought over it.

In the two days after the episode aired, we sold more razors than in any month before it. Half a million sold since.

Same razor. One blade, cutting at the skin's surface. Built to last decades, guaranteed for life.

How it Works

One blade, built to last a lifetime

  • 1

    Load a single blade.

    The injector slides the blade into place and locks the angle. You never touch the edge. NickStop fins regulate how much skin meets it.

  • 2

    Shave with the grain.

    Let the weight of the solid-metal handle do the work. Less pressure, shorter strokes, one clean pass.

  • 3

    Swap for about $1

    Replace the blade when it dulls, 8 to 10 shaves per blade. With this offer, your first year of blades ships free.

Guaranteed for life

If it ever fails, we replace it. Forever.

The Single Edge is a solid piece of metal with no moving parts to wear out. It carries a lifetime warranty, and a 30-day money-back guarantee - longer than the learning curve. If the shave isn't for you, send it back for a full refund.

Questions

Before you decide.

Is a single edge razor right for me?

 If you deal with irritation, razor bumps, or ingrown hairs - or you're just tired of paying for cartridges - yes. GQ named the Single Edge SE its Best Razor for Sensitive Skin for 2026. Plan on five to ten shaves to learn the angle. The 30-day money-back guarantee covers the whole learning curve.

How much do blades actually cost?

About $1 each, and one blade lasts 8 to 10 shaves - pack of 8 covers about three months. About $32 a year in blades, plus $5.99 shipping per delivery. Brand-name cartridges run $100–$200+ a year.

What if I don't like it?

You have 30 days to try it - longer than the learning curve. If the shave isn't for you, send it back for a full refund. The razor itself is guaranteed for life.

Is this the razor from Shark Tank?

It is. We pitched the Single Edge on ABC's Shark Tank and walked away with a deal. Same razor, now with 500,000+ sold and 4.7 stars across 4,000+ reviews.

Do I have to buy Supply blades?

No. The SE takes any standard injector blade. Buy them from us or anywhere else. The free year and the subscription just mean you never have to think about it.
