I Spent 3 Years and $400,000 Trying to Solve the One Problem No Razor Company Wanted to Talk About

A former engineer's obsession with razor burn led him to invent a head and body shaver that shouldn't physically work — but does.

The first time I shaved my chest, I was 19 years old and getting ready for a beach trip with friends.

I figured it would take 10 minutes. A quick once-over with the same razor I used on my face, a little body wash for lubrication, and I'd be done.

Two days later, I was sitting in a doctor's office with what looked like a constellation of angry red bumps spreading from my collarbone down to my stomach. Some of them had started to weep. A few were infected.

The "before" photo I kept on my phone for 12 years. Different decade, same problem — every time I shaved my chest.

The doctor — clearly trying not to smirk — said something I'd hear from dermatologists for the next decade:

That answer was unacceptable to me. Not because I needed to be hairless to feel good about myself — but because it was 2008, we'd put a rover on Mars, and somehow the best advice a medical professional could give me was "just live with it."

So I started a hobby. The hobby became an obsession. The obsession became Exoshave.

This is the story of how I spent three years and over $400,000 of my own money trying to crack a problem that the entire shaving industry had quietly decided wasn't worth solving — and the moment I realized the answer wasn't a better blade. It was a completely different kind of blade.

The dirty secret of the men's grooming industry

Here's something the razor companies will never tell you in their commercials:

Every razor you've ever used was designed for your face.

That's it. That's the whole industry. The blades, the angles, the lubrication strips, the pivoting heads — all of it was engineered around the assumption that you'd be dragging it across cheek skin, which is one of the most forgiving surfaces on the entire human body.

Your chest? Your back? Your shoulders, your stomach, the inside of your thighs?

Completely different territory. Body skin has:

• More hair follicles per square inch
• Hairs that grow in chaotic, multi-directional patterns (not a single grain like a beard)
• Thinner skin in some places, much thicker in others
• Far more friction points from clothing
• Way more sweat and bacteria

Me, about 18 months into prototype #7. Still frustrated. Still hairy. Still convinced there had to be a better way.

When you take a face razor across that terrain, here's what actually happens:

The blade slices the hair below the skin line. The follicle, now sealed off, starts to heal. The hair inside keeps growing — but it can't break the surface. So it curls back on itself and starts growing sideways under your skin.

That's an ingrown hair. Multiply that by a few hundred follicles. Add bacteria from a blade you've used 6 times. Add friction from your shirt rubbing against it for 8 hours.

That's razor burn. That's the red bumps. That's the itching that wakes you up at 3 AM.

And the worst part? Every razor company knows this. They've known for decades. They just don't sell a solution. Because the solution isn't a better razor.

The $400,000 mistake

When I started Exoshave in 2021, I thought the answer was obvious: just build a really, really good electric trimmer.

I had spent years in product engineering. I'd worked on consumer hardware. I knew suppliers in Shenzhen. I figured I'd source the best motor, the sharpest blades, the most ergonomic grip — and call it a day.

Three prototypes in, I realized I was building the same thing every other brand was building.

The problem wasn't quality. The problem was physics.

Every traditional electric shaver — even the premium ones — has the same fundamental design flaw: the blade has to be pressed against your skin to cut hair. That pressure is what creates the friction. The friction is what creates the heat. The heat and the micro-abrasions are what create the bumps.

You can make the blade sharper. You can make the foil thinner. You can add five different "skin guard" technologies. But as long as a piece of metal is being mechanically forced against living tissue, you're going to get irritation.

I spent eight months trying to engineer around this. Different blade angles. Different oscillation frequencies. Ceramic coatings. Diamond-like carbon. I burned through $180,000 just on materials testing.

Nothing worked. Not really. I almost quit.

The conversation that changed everything

In late 2022, I was at a trade show in Frankfurt, half-drunk and venting to an old colleague about how I was about to shut the company down.

He's a magnetics engineer. Spent his career working on industrial sensors, MRI components, that kind of thing. He listened to me complain for about 20 minutes and then said something I'll never forget:

I didn't get it at first.

He drew it out on a napkin. If you suspended the blade in a magnetic field — not held in place by springs or screws, but actively floating between two opposing magnets — it could move independently in seven dimensions of motion. Tilt forward, tilt back, slide laterally, rotate, pitch, yaw, and most importantly: retract under pressure.

The blade wouldn't be pressed against your skin. Your skin would simply make contact with a blade that was suspended in space, free to give way the instant it felt resistance.

No mechanical force. No friction buildup. No heat.

I flew back to my workshop the next morning and didn't sleep for four days.

Introducing MatrixGlide7: the technology that shouldn't exist

What we built — after another 14 months of prototyping, three patent filings, and roughly $220,000 more — is called MatrixGlide7.

It's the core technology inside every Exoshave head and body shaver, and as far as we can tell, nothing else like it exists in consumer grooming.

The MatrixGlide7 blade head. Seven double-edge floating blades, suspended in opposing magnetic fields. No springs. No screws. No friction.

Here's the short version of how it works:

Two opposing neodymium magnets suspend a double-edged blade inside the shaving head. The blade isn't bolted in. It isn't spring-loaded. It's floating — held in equilibrium by magnetic force.

When the shaver touches your skin, the blade responds to seven distinct axes of motion in real time:

• Forward tilt — adjusts to skin angle as you move
• Backward tilt — same, in reverse
• Lateral left & right — follows curves across chest, shoulders, back
• Rotational pitch — wraps around contours
• Vertical retraction — pulls back the instant it senses too much pressure
• Free-floating pivot — eliminates the "snag" point that causes nicks

The result is a shave that feels closer to a wet razor than anything electric — but without the friction.

Because the blade is double-edged and floating, it cuts in both directions. You don't have to make multiple passes. You don't have to go "with the grain." You glide it across your skin once, and it captures hair from any direction it's growing in.

But the number that matters most to me is that last one. After 12 years of bumps, scarring, ingrowns that needed to be lanced, infections, and embarrassment — zero.

Why "7D magnetic floating blade" actually means something

I know how this sounds. Every shaver on Amazon claims to have some kind of proprietary technology with a number in the name. "5D flex." "6-direction pivot." "Triple-action whatever."

Most of it is marketing nonsense bolted onto the same basic mechanism that's been used since the 1960s.

What makes MatrixGlide7 different — and I say this as someone who would have happily knocked off an existing design if it had worked — is that the floating blade actually changes the physics of the shave.

Mid-shave on my own chest. No drag, no tug, no heat. Just one pass.

Traditional shavers: blade is fixed → skin deforms around it → friction → heat → irritation.

Exoshave with MatrixGlide7: blade floats → blade deforms around skin → no friction → no heat → no irritation.

It's not a marginal improvement. It's a different category.

The double-edge design also means the blade lasts roughly 3x longer than a single-edge equivalent. You're rotating wear across two cutting surfaces instead of dulling one. And because the magnetic suspension has no mechanical contact points — no pivots, no springs, no friction joints — there's almost nothing inside the shaving head that can wear out or break.

What this actually feels like

I want to be honest with you, because I hate marketing copy that overpromises.

The first time you use an Exoshave, it feels strange. Almost too smooth. You'll catch yourself going back over an area because you don't believe it actually cut the hair — and then you'll feel it, completely bare, no stubble, no irritation.

There's no tugging. No vibration in your hand from the blade fighting your skin. It feels almost frictionless, like you're running a smooth river stone across your body.

Two months after I started using my own prototype. No bumps. No redness. No follow-up creams. Just smooth.

For head shavers, the difference is even more dramatic. The 7D motion means it follows the curve of your skull continuously — no flat spots, no missed patches behind the ears, no nicks on the crown.

For body grooming — chest, stomach, shoulders, back (with the extension handle), arms, legs, anywhere you've ever had problems — it just works. The contours don't matter. The hair direction doesn't matter. The blade adapts to you in real time.

It's waterproof, so you can use it wet or dry. We recommend dry for the absolute closest shave, but wet works beautifully too, and you can use it in the shower. A single charge lasts about 90 minutes of active shaving — for most guys, that's 4-6 weeks of regular use.

Why I'm telling you all this

I didn't build Exoshave to compete with Gillette or Philips. They have hundred-year head starts and billion-dollar marketing budgets, and I'm a guy who started a company in a garage because I was tired of being embarrassed at the beach.

This summer. First beach trip in over a decade where I didn't spend three days dreading the aftermath.

I built this because for 12 years, I lived with a problem that the entire industry told me wasn't solvable.

And it turns out it was solvable. It just required someone willing to throw out everything we thought we knew about how a razor should work, and start over from physics.

If you've ever:

• Gotten red bumps after shaving your chest, stomach, or shoulders
• Had ingrown hairs that wouldn't go away
• Been told by a dermatologist to just "live with it"
• Switched between razors, trimmers, and waxing trying to find something that doesn't hurt
• Avoided shaving your body entirely because the aftermath wasn't worth it

…then this was built for you. By someone who's been exactly where you are.

I can't promise you it'll change your life. But I can promise you that the next time you shave, you won't recognize the experience.
