Your hair can crack steel when it hits the right spot 

Literally all the waste from razors is due to the fact that the cartridge system makes the company the most money and has the most marketing. Anyone that has tried a decent safety razor knows just how much better it is and enjoys the freedom of not having to worry about blades being crazy expensive or being discontinued.

that's literally cutting-edge research :)

“With new blades we can cut that waste off at the source.” I see what you did there.

Wiping dry your razors will vastly increase their lifespan. Drag them in the opposite direction on a towel.

Razor makers don't want to make longer lasting razors because they want to sell more razors. This is called planned obsolescence.

it’s so soothing to watch hair crack steel

The trick I learned that saves money and environmental waste is an old school double edge razor, doesn't take long to get down, a 10 pack of blades is around $5 or less, far less plastic waste

Waste-reduction is a big driver in my use of straight razors, steel tools that can be rehoned across lifetimes. Unfortunately, I've also accumulated a pile of shave soaps, most of which come in . . . plastic . . . tubs.

2:05 "working to create longer lasting razors" Way to put a target on their backs for Gillette's snipers

lol the hair under the microscope black and white looks like metal rebars!

I woke up from a weird dream thinking about razors and blades. I remembered watching a StarTalk episode where they talked about the relationship between surface area and pressure. The smaller the area, the higher the pressure. I was wondering if razors manufacturers design blades so the surface of the tip is just small enough to cut the hair but not too small that it can be extremely hazardous. I woke up hoping someone took a blade under a microscope to see my theory and here I found this amazing video. This perfectly fits the idea discussed in the episode. In theory we can design a knife blade that will cut a tomato in half without applying any force. The force resulting from the weight of the knife maximized by a small surface (of the sharp edge) will result in high pressure. But this giving that it must sit on a 90 degrees angle as mentioned in the video.

As an experiment, I reused the same disposable razer for almost 3 years. The only thing I changed was I sharpened it for less than 5 seconds every time I am about to use the razer. Literally takes 5 seconds. It stayed sharp enough to be comfortable all that time. The plastic eventually broke and that's the only reason I needed to change it. If you want to cut your expenses on disposable razors I highly recommend simple sharpening yourself.

While you were shaving your neck beard, I was here, studying the blade

It's like printer ink cartridges. It's makes money for the companies.

They don't make strong razors so u will be forced to buy again..

Mature men don't use razors that have any plastic attached to them, thus the blade waste is merely steel - and that can either rust away, or be recycled.

There is already tech to make razor steel last way longer then what we have. But if they use it the wont sell anymore razors

There is a technique from Ranma 1/2

Tip: use safety razors. They will save you money and the environment

Or you could just go back to using a double edge safety razor. Blades are about ten cents each can be used multiple times and are 100% recyclable with no plastic waste. Not to mention that you get a better shave :)

I hope that the researchers will have success :D

Well thats because the razor blades arent monocrystalline. I see two choices here: Either a monocrystalline blade(just so u know, jet engine blades are monocrystalline) Or katana-like metal folding. It would help bending the crystals to form something like a filament bunch (just like katanas). That said, wouldnt solve the problem but at least would be helpful in reducing the stress on the blades.

What happened to having titanium blades from twenty years ago? Mine still works just like new.

I just shave through the skin under the follicles, never had to replace a razor ever since.

Porque una hoja desgastada no corta bien el pelo pero si puede causar cortes de piel?. Cuál es la explicación física ?

This seems like a video that'll get a million views from the algorithm.

So you’re telling me that my hair.. can stop a knife.. I know what I must do......

I have a shaver

Love the video!!! Can you do other videos on hair and skin please 😎

For a set of 4 blades.. the first 3 have a limit of 1 week each.. but the 4th blade, it actually could last for a year...

those fusion blades are TOO thin and the blade will always fracture! it's like taking a bat to a thin piece of sheet metal and punching a hole through it!

If you see this comment, do yourself a favor and switch to a traditional double edge razor. You can buy a 100 pack of DE blades on Amazon for less than 10$, and with proper technique, they will give a better shave than any cartridge razor could.

People should try switching to safety blade razors, at least there is no plastic waste and you definitely get more shaves per blade vs disposables. I switched about 8 years ago and haven't looked back. I mostly use a 1960s Gillette Slim Adjustable which is my favorite, Parker makes decent modern safety razors but don't compare to old Gillette's in my experience.

Defendor razor is the best i had 6month shave on just one unit they probably use the same technology

How unusual . . . They had someone grow a beard to investigate the beard / blade interaction. I’m mystified.

Or just use metal razors, way better for the environment and the razors are replaceable

Could rust on the edges play a role as well? Placing the cartridge dipped in oil may avoid rusting.

It’s like cutting trees the axe can get dull after lot of swings

Need some Magnacut razors

Very informative.

This was awesome 👌

Stretch a wire and as you're stretching it make an edge they'll give you a razor that is so good at cutting hair that'll be difficult for her to get worn down

Is there any good examples of other mammals that have similar hair growth as humans with mostly only like head and facial hair that grows exceptionally long compared to other parts of the body?

Put a really friggin strong vacuum on a razor so the hairs and tugged into a position perpendicular to the blade. Betcha a dollar it makes the blades last a lot longer.

Is this true across all razor brands???...

I must have thick hair my razors are always one use. Got tired of replacing razors so many times so I’m going mountain man style lol

Very interesting!

myr razor only gives me one shave before i have to toss it and get a new blade but they are like a cent each.

Ha I'm lucky to get 3 shaves with out feeling like it's pulling my hair out

Electric shaver is the superior way to shave. You dont need foam, its faster, cheaper. You can shave everyday in 30 seconds and never have to buy a razor again.

is this thr same way on skin? asking for a friend

best practise is to make something cheaply and disposable, sell expensively. Accumulate great wealth.

Diamond tipped razor blade when?

Lovely

so the traditional manufacturing has to have a razor thin margin of error to deliver a cutting-edge blade.

Or they can simply make the blades from a better steel.

Misleading title, steel is the subject and defects.

neat

Human hair is harder than steel

Just get an electronic razor. I never understood the others.

Whiskers are as hard as copper wire of the same guage.

Gillette! A stunning image here makes me seeing is hardly believable! Some edge in the footage!

Everyone knows side loads chip blades..

"They work on creating longer lasting razors" damn that's a silly lie to forward. It will never happen, it's just good business.

Big shave would never allow good blades

What about titanium?

Grow a beard.......Save the planet

İngiltere kralı, rahmetli başkan Kennedy, taçsız kral Pele, Beckenbauer, Kaleci Mayer, Nadia Komaneci, Brigitte Bardot, Fenerbahçeli Cemil

Metal can be chipped after 50 hair..

Cutting Edge Razor Commercial fu*k y m I watching this

I have so many questions as a researcher. One of which is- Who funded this research? Because, any findings are irrelevant to help humanity in any way. Money and time would've been better spent elsewhere. Shaving isn't a necessity. Want to reduce wastage of blades? Just don't use them!

00:08 because you don’t clean them right

Designed failure

Science oddities or science fiction !? Duh !!

I only wish this information would get more views from the general public than Dr Pimple Popper or some such nonsense.

I could do it with two steel balls from ball bearings

Cool. Can you work on a cure for tinnitus now?

This is why alot more people the last 20 years have "razor bumbs" it'd cause of cheap metal getting lodged in their pores causing a lifetime of agony.

I shave my face with a honed axe, no shaving cream, no water, just 100% axe.

Or have a beard or get a knife.

No its cheap metal all the way.

The answer to razor waste: shave like a man with a straight razor. One blade can last multiple generations.

I hope gillette dont have this problem

I feel like "cutting the waste off at the source" would look more like accepting the inevitable existence of facial/body hair. But I suppose a longer lasting razor is a realistic compromise. Maybe we could even find a way to use 1 nice blade instead of relying on a row of 3-5 crappy disposable ones. Here's to hoping, and thank you to everyone who had a part in those incredibly satisfying macro shots.

Oh and about the environmental importance. I really hope that the reason people throw away razors because they're not sharp. I believe the reason actually because they think it's dirty/contaminated.

I have a beard now I know I'm saving the environment. Nobody better ask a bearded man to pick up his garbage or buy an electric car . We are doing our part and have been for a long time.

I hate shaving

*Or* we could all just stop shaving.

Shaving is unnecessary anyway. Shaving is just a marketing gimmick.

Fake

The steel used in razors is garbage, we know this now, make a razor in cpm rex 121 steel and it will last a lifetime without sharpening, or better yet, tungsten carbide, or certain new high grade ceramics, there, problem solved, one razor for life, garbage steel sharpened at extremely acute angles will dull and chip fast and often, we know this now, he'll s30v would be better and last a very long time, or cpm s110v, cpm s90v, lc200n, cpm m4, cpm cruwear, cpm magnacut, cpm 4v, I could go on and on with tons of modern powder metallurgy produced super steels that can do the job, hold an acute angle and not wear or chip hardly ever if all that's being cut is hair, scientists and companies know this, they know the technology and steel exists, they don't want to make quality products that last a lifetime, they want you constantly buying and throwing away and rebuying there garbage product, imagine if every young man when they started to need to shave bought or had bought for them a 30$, $50, $70, or $100 dollar razor made of cpm red 121 or tungsten carbide that lasted them a lifetime, there businesses would collapse, and for all those that say those metals would cost way to much, no, disposable razors have a couple of super thin, very small pieces of metal, a disposable razor with cpm rex 121 should only cost about 5 to 15$, and last 10 to 15 years or longer,

Or, now hear me out, get a straight razor that will last a lifetime and can be passed down through generations. Problem solved. And you get a closer shave than the disposable razorblades.
