A small blade safe can hold hundreds of blades and it’s like 4"x3"x3". Makes sense they thought the inside of drywall 5’x3’x1’ would be fine. It can probably hold tens of thousands. Even with a new blade daily that’s decades. And when you tear down the wall you’re dealing with Sheetrock, nails and screws already. All that time would have dulled the incredibly thin blades.
This is all to say: it seems wild but was a decent idea.

Hundreds of thousands
yeah I have one that’s a few inches cubed for 6 years now and it’s nowhere near full.
Wall full of tetanus.
Wall of Tetanus is a pretty sick 5th level spell.
It’s also a pretty good name for a metal band
here are some metal fonts to choose from

Safety razors with disposable blades were introduced about 120 years ago, at one blade a day that’s a bit less than 45000 blades
Double edged blades dimensions are: 0.1mm x 42.7mm x 22mm for 98.21mm³
45 000 blades would take a volume of 4 419 450mm³ or about 270in³
A regular indoor wall is made of 2x4 and each stud is 14.5 inches apart (16 inches on center). A 2x4 is in truth 1.5" x 3.5" so each inch of height inside the wall is 3.5 x 14.5 x 1 which is 50.75in³
45 000 blades stacked perfectly would therefore use 270 / 50.75 = 5.32 inches of the wall’s height… So even if they didn’t stack perfectly, it’s pretty safe to assume that there’s enough space inside the wall for hundreds of years at one blade a day (especially since old houses usually used true 2x4 and had their studs at 24" on center)
One blade a day?!! Are you a billionaire or something? The acceptable signal to replace the razor is when the pain from the dull blade pulling your hairs makes your eye watery, and then you try to man up for a couple more shaves before accepting defeat and put in a fresh blade.
It’s an exaggeration to show how long it would take to fill a wall
Multiple homes I’ve lived in have had these slots in the medicine cabinets lol.
Did they anticipate people not living long enough to care? Or that some biome would form to use the blades as food?
Interesting decisions all around.
Prevents them from being mixes in with general garbage and people cutting themselves when handling such.
Makes sense!
They are very slim. You would really need to shave a lot to see it being full.
I use these blades to shave almost daily. I use approximately 40 each year. I would never be able to fill up a wall with these, not even during 10 lifetimes
I think this is the first real TIL for me in ages.
Congrats ☺️
Remodeling contractors hate this one trick…
How bad could it be? They’d all be piled up at the bottom of one stud cavity and you know they’re there. If you’re demoing the wall you’re gonna have gloves and a shop vac and a bigass broom and shovel anyway.
Still I got a little blade bank (about the size of those mini soda cans) on Amazon for $7 for my double-edge blades. Last year. And it still has plenty of room in it. Supposedly it holds 300 blades. That’s two blades a week for nearly 3 years. An absurd frequency…I replace my blade every week and I shave my head and they could totally go longer, they’re just so damn cheap.
I think these plastic boxes the blades come in often have a slot for used blades on the bottom. They take up so little space without the paper around them that an entire pack fits into a 1mm slot maybe.
Not just hotels but houses too. There would be a slot inside the medicine cabinet for disposing razors into the wall. Dude who came up with the idea was probably like, “we’ll all be dead from nuclear bombs before any of these fill up or needs to be renovated”.
They predate nukes, bro.
Came to say that. Was very common for a long time.
Yeah we had a 1920s house with a metal medicine cabinet above the sink. It had the razor blade slot and yeah they literally fell into the wall between the studs.
This was behind the medicine cabinet in my house.
Idk why but this bothers me
Because they owned the house for who knows how many decades and only used 9 razor blades?

I still use safety razors. I get all excited when I’m at a bathroom that I can slip one in the wall.
Safety razors are the best! They are cheap, you can buy a bunch of quality blades for pennies compared to a “Mach 3” or whatever.
Once you learn how to shave with one, there’s no going back.
What’s different about shaving with one as opposed to a regular disposable?
Cost! The cheap disposable blades are horrible to shave with. The good ones are crazy expensive.
Good quality safety razors are cheap! I bought a pack of blades and it’s lasted me literally years. It probably cost me $10-15 too.
I thought people use those plastic blade disposal container that has a slot on top that you throw away once it gets full nowadays.
It’s not built into the wall, but the base principle still hasn’t changed even after all these times.

I use those blades in present day.
When I put in a new blade, I keep the wax paper wrapper, then rewrap the discarded blade in said wax paper before discarding it.
Give or take twelve years into this endeavor, I’ve had zero issues with this system.
I put all my used ones in a clear pill bottle. Plan is to burn them in the next campfire I have so that they never enter the waste stream.
You’re joking, right?
Why would I be joking? Razor blades will oxidize into nothing in a fire
That’s brilliant! We should burn all of our garbage so nothing enters the environment!
I’m not suggesting burning all trash, I’m suggesting burning a miniscule amount of steel to avoid the risk it poses to human and animal life. It turns into iron oxide (RUST). The fire pit ring itself will have about 100x as much of it.
Sharps disposal literally exists for this reason
Steel would also office without fire
Where do you think the rust goes in either case?
I literally don’t have sharps disposal available to me. The rust will mix with the ash and become dispersed harmlessly into the soil. Look at an iron ore mine and you will see millions of tons of iron oxide, because that’s how iron is usually found in nature.
Safety razors are great! They’re way cheaper than “conventional” (3, 4, 5 blade) razor blades. They shave a lot closer, and you can get a variety of different grades of blades to fit your comfort level.
The only reason the expensive multi-blade disposable razor cartridge became popular was because Gillette enshitified their razors to maximize profit.
I have this (I am sure irrational) fear that if I use a safety razor, I will cut the shit out of myself. Which, I realize, goes against the word ‘safety’ in the name.
You do have to be a little more delicate because it is easier to cut yourself but it doesn’t take long to get a feel for it. I doubt I cut myself any more than I did with a 4 blade cartridge.
I’ll have to try to get over my fear and try it. How does it do when you haven’t shaved in a few days? Because I’m very lazy about that.
It takes a few weeks for your face to get used to being shaved by a safety razor but once it is, my god.
It’s like the MSPaint Erase Tool in real life. I used to do electric razor only going over and over and over
Now it’s like almost pornographic how easy it is to shave – one swipe down, two, three, four… half the face is hairless.
Four swipes left, left side is hairless.
Four swipes under the moustache and bam.
Highly recommended getting over the beginner’s curve, watch some YouTube videos but here’s a Linux primer on how to do it:
- Fill shaving cream bowl or basin with warm (not hot water).
- Allow horsehair brush to soak in basin for 1-5 minutes.
- Shake excess water off the brush
- Add about half a toothpaste brush amount of shaving cream to the basin, stir into a rich lather, consistency of yogurt. If it’s foaming up/running there’s too much water. I recommend PRORASO, Menthol (Refresh). One $10 tube lasts 3-6 months. Extremely cost effective.
- Run some warm/hot water on a very low pour from sink. This is used to wash hair off your razor between passes.
- Sterilize your safety razor with a 55-75% isopropyl alcohol spray. This is optional but prevents any kind of infections, because these razors basically slice open everything including pimples.
- Lather up your face. Sides, bottom, moustache, whatever.
- Don’t apply excess/heavy pressure, these razors are extremely sharp. Go down in a stripe, flip razor over, do another stripe. Down cuts hair, holding at a mild angle, across (left right) cuts your skin, so never try to slide the razor across your face.
- Go slow, practice, once your face is used to it, it becomes second nature and shaving is 10× more pleasurable and convenient than those disposable razors or whatever.
- It’s good enough that I recommend it to other people. I’m a man, few things make me actually feel like a man more than a good/proper shave.
