    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”.

    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.

    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.

      Also, most people use blades for more than one day’s shave. I think more like 3 - 7, depending on the blade and how picky the shaver (I get more than seven shaves per blade).

      0.1mm seems awfully thin for a double edged blade.

      It’s also unreasonable to assume they will stack anywhere close to perfectly.

      My guess is you’re off by at least a factor of 20.

          The year is 1950. A veteran of World War II has come home, married his best girl, gone on a whirlwind honeymoon to exotic, far off Daytona Beach, then like many people in this time, picked a location and built a house. Then he’s recalled to service to go fight in a place called Korea, and never returns. His widow never remarries. Most of a century later, the next owners of the house wonder why there’s so few razor blades in the wall.

      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.

    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?

        It’s not so much about filling it up, but when someone goes to eventually renovate the place lol. Open the drywall and just have a bunch of blades to clean up… Or if you get a leak and have to now deal with a puddle of rusty blades.

        I want to say that possibly one of the medicine cabinets had a smaller container that collected them at some point, but again, it was still fixed behind the wall lol.

        Its like a solitary confinement torture dungeon, but worse. Its a narrow pit below the dungeon where they toss people who are condemned to death. Too narrow to sit or lie down, even if your legs got broken when or before you were thrown in. All sorts of shit piss gore and blood get tossed in too. Probably other harmful junk like live rats and broken glass. There is no return, and they dont clear out the previous tenant or remnants thereof before the next one is moved in.

      They probably shaved about the same but mostly used double-edged (100% steel) blades that could easily fit in a slot, rather than the plastic-clad, quadruple-blade nonsense sold for $8/cartridge.

      You can still buy double edged razors for about 10-15 cents apiece, by the way.

        15¢ per double edge blade is high unless you’re only buying 10 or 20 blades at a time. Get the 100 count pack and you’re paying under 7¢ per blade… Each blade should easily last 3-7 shaves depending on your hair, more if you have tough skin ;)

          Dude I’m 38 and I’m surprised everybody doesn’t at any age.

          I shave my head. I’ll admit I had to unlearn some habits from cartridge shaving. First couple of times my head was a bloody (literally) mess. But once I got technique down, it’s easier and faster than cartridge shaving.

          What slows me down over “the modern way” is that I whip my soap with a brush and bowl. That’s a little less convenient than shaving cream/gel, but it’s optional. No reason you can’t use canned foam/gel. Holy shit is it cheaper though. I ordered a 3 pack of cheap shaving soap (3.5oz bars, $10 total) last January and I’m not even halfway into the second bar.

          Best part is, less waste. No plastic. Every handle I’ve seen is all metal and even the cheap ones feel better in the hand. Stainless Steel Blades are wrapped in wax paper and packed in a little cardboard box. Soap gets shipped in cardboard boxes.

          Literally no reason not to.

            I just dry shave (safety razor) and it seems to work well for me. Less hassle + blades don’t rust so they last longer

            I also heard that the blades can be sharpened by running it against trousers or something like that, so it is possible to reuse them / extend their lifespan

              It’s called honing and you can hone a blade on a piece of leather, like an old belt. It’s not sharpening per se, but it keeps the little burs on the blace’s edge lined up nicely so it stays sharp and if kept up, prevents the need to sharpen with something more aggressive like a sharpening stone (or the bottom of a coffee mug in a pinch).

          Yeah used DE since my grandpa gave me one of his when I was like 13, his father was a barber by trade and I also have his straight razor collection (which I don’t use).

          Actually use a mix of DE, disposable, and electric, depending on the purpose. The Philips oneblade and classic Andis foil for face and jawline with finishing DE touch on flat areas sometimes. I know electric on face… used to have acne too but I find they keep my skin barrier more intact by barely not getting to the skin.

          I legit use the double edge on d+bs more than anything… sounds like a bad idea I know but for me it’s the easiest, quickest, far superior result, and way less injury than any other method. You maybe wouldn’t think this but going on every 3-5 days for like 10 years at this point so I’m completely confident in it. An electric with shortest attachment for pubes and around the edges, then the DE on genitals, nothing better.

          First couple of times I had to unlearn some old habits. Was a bit of a mess. But that was mostly in my scalp. My face was largely fine (to be fair, I have a beard, so it’s just cheeks and neck that gets the blade).

          After my technique improved, though, I get nicked about as often as I would with a cartridge.

          The hardest part was finding a blade that worked well for me. There’s a ton of variation in the blades. Once you find a brand you like though you tend to lock in. I bought a bunch of sample 5-10 blades from the most popular brands (feather, astra, gilette, tiger, etc). I ended up settling on Gilette Silver Blues. Ymmv.

          Nah. It takes a little more awareness while you’re shaving for sure, but you’re rarely if ever going to cut yourself once you get your gear and technique dialed in. For me, I had to find the right blade. I found Feather brand blades, which a lot of people recommend, didn’t work well with my skin, but Astra blades are great for me. Everyone’s a little different.

            I also like the Astra blades. Even more important ive found is a quality razor holder. I had a few, but when I got a Henson for Christmas it was the best shave I’ve ever had. Their marketing isn’t a gimmick. A well supported blade held rigid doesn’t flex and pull at hairs.

              My Merkur 23C has served me well for 13 years. Recently the threaded screw broke off and I had to get a replacement head. But it was very reasonable. I have been curious about the Hensons, but have tended to stick with the “if it ain’t broke, don’t fix it” philosophy. People really seem to like them though. Do you have the light, medium, or aggressive?

                I have the standard AL13. I didn’t know they had different levels. My beard isn’t super thick, but not sparse either. I can shave a full weeks growth (4-6mm length) without issue. My previous razors would clog a fair bit if I did the same and I’d have to take less per stroke and rinse more frequently.

                  I couldn’t resist. I went ahead and bought that AL13 aggressive after reading and watching a bunch of reviews. It’s great. It holds the blade more firmly than the Merkur and shaves really smoothly without pulling. I would like it if it were a bit heavier, but it still feels good in my hand. Thank you for the recommendation.

          There’s a bit of a learning curve, but just be cautious at first and you’ll figure it out. It’s not rocket science. Also don’t use dull blades as that’s an easy way to cut yourself. Fortunately they’re dirt cheap.

          I’m talking about double-edge blades that fit into a handheld razor that looks a lot like a Gilette or Bic, except it’s all metal, and about 2% of the price per blade, not a straight “safety” razor that you might see a professional barber use.

          I would be too lazy to shave every day (and sometimes I am) but I get skin irritation if I don’t shave. Could use some strong ointments as a temporary fix but those are not good to be used too often. My dermatologist said that as long as shaving helps I’m better off shaving

      It seems like a presentable person was supposed to shave twice a day, in the morning and after work. Considering that you need to make three passes to shave well it would make 6 passes a day.

      I tend to replace blades after about 5–10 shaves, so 15–30 passes, but I heard of people replacing after each pass. Some brands may also stay sharp for longer, giving even more spread to numbers.

      All-in-all, it seems like one can expect to produce from 70 to more than 2000 disposed blades per year. At a thickness of about 0.1 mm it would be something between 7mm/year and more than 0.2 meters/year

      Now I really think that even the most sensitive skin doesn’t require you to change a blade after each pass. I also find it hard to imagine producing a pile of blades a meter high in 4.5 years

      They shaved more often in the old days I presume…

      People were hairier thousands of years ago.

    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?

          They’re much less irritating to your skin. Disposable razor commercials sold the world on the idea that more blades=closer and smoother shave; when in reality they can really tear up your face and leave razor bumps and ingrown hairs.

            Do they really not make any with a swivel head? That’s a pretty useful feature imo, and certainly would be easy to design for on a safety razor.

              I’d say it’s more of a learning curve question. With a swiwel you get good results most of the time but if it doesn’t work as you need there’s nothing to do. With a solid construction you need to learn to manipulate it efficiently but then it’s that you can use it for any shape of skull. TL;DR convenient ≠ better

                I’ve literally never once had a swivel head razor that didn’t work.

                It really seems like a stretch to make this into a skill issue lol

                  Yeah, I have the same leg but it doesn’t hurt

                  But yes, it’s better I elaborate: it’s not the razor that may or may not work. It’s the user that may not be suitable for swiwel head and such a user will be equally bad suited for all of them. It’s good if it works for you but not guaranteed to work for others

          Just crazy cheap. I spent probably 5 dollars on shaving last year. That’s using the most expensive blades made.

          Very cheap, and I find if you leave your beard too long before shaving, hair doesn’t get caught either (it can’t really)

          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’ve been using DEs for the last 6 years. I use a Feather blade in the shower with no mirror to fully shave and don’t cut myself. Not saying when I started I was that good. Feather blades are extremely sharp. I walked out pretty bloody once or twice when I started using them. Just get really good on some 7o’clocks or Gillette blades first.
