How to Make Simple and Effective Stone Tools | Big History Project 

My life is so sucky rn that I would love to get stuck on a bloody island

Society is gonna go to ahit soon so it is wise to educate yourself on how to survive on your own.

Lol

Good for you - your comment is 8 years old as of mine here, so your 11 year old is now 19. Hope you're both doing well - you sound like a cool parent. It's amazing to think of our very distant ancestors that _all of us_ very nearly 8 billion people now descended from, beginning to create this very basic technology, that eventually blossomed into the laptops and smartphones we're using to communicate on this site, right now, to the point we're on the cusp of landing humans on another planet, ~60 million miles away at its nearest point. Even long, long, _long_ before them, three billion or so years ago, what's called the Last Universal Common Ancestor (LUCA) lived - and from that very simple, single-celled organism, literally all life on Earth descended from, was nearly wiped out several times by asteroid impacts, shifts in climate, super volcano eruptions, etc., only to survive, evolve, and eventually lead to all of human civilization, billions of years later.

You need to find stones which will produce a concoidal fracture when struck. con·choi·dal /käNGˈkoidl/ adjective MINERALOGY denoting a type of fracture in a solid (such as flint or quartz) that results in a smooth rounded surface resembling the shape of a scallop shell.

Search in spring , I just learned , rocks spall , from frost heave , large thin flakes , each year ,good ones can be found , look for the glass like break in the stream bed samples , then look for that sound , Goode stone rings .

Sandstone just requires a different technique. Rather than knapped, sandstone grinds very well. If you make a basic corded pump flywheel spindle drill, and affix a round flat gritty piece of sandstone to the base of it, then a secondary crossbar+peg to rest upon your knees below your pump bar, you have a rotary grinder that will let you put an edge on a piece of sandstone fast with lower exertion, you just position and angle your sandstone being sharpened with your feet, angled against the outer edge of your spinning grindstone from your pump drill. It's not as great for the kind of surgical edge a good conchoidal fracture gives, but the ease of resharpening makes it excellent for heavier and more durable axe and hatchet blades. And after enough use your round grindstone itself can then double as an excellent circular saw.

@j Tom Waits for no man.

Use the sand stone to file down your blades

It’s really not that intensive. I can knock a nodule to a quarry biface or “flake core” in a matter of 10 minutes.

The objective is to thin it as rapidly as possibly and this guy isn’t setting up his platforms properly or holding the piece with enough support to drive flakes across the median of the piece.

yep

mhm

Omg same lol 😂

Yepp

POV: You came here yourself because you ain't no bitch nigga

Lmao

No maybes by diving or digging deeper we will come to the science telling and actually revealing to us that we humans come from the dark ages.., we strong ones all crept and crawled, struggled oh and some fought there way out of some hell like type of place, did you'll ever wondered why space is so much and actually overpowers light look beyond the blue skies that we can see from down here on earth...it's all black and darkness out there...''the dark ages''

Earlier than that we all come from star stuff

U should try digging up these artifacts

@@hunter7527 nah, it's all overgrown with thick & dense Amazon forest, and people would see and think of me as some other maniac suffering a new form of gold-rush or so, But it depends on if I get the permit, because In my mind it still rattles that the beginning of our humans in the being form that we now have comes from here ''south-america'' by only joining the continent's to each other in the imagination we from Suriname back in the days could have hopped on a camel or an ox back an travelled to Jerusalem It wouldn't even be that absurd long of a journey if, only if the continent's were still joint to each other

@@jchrg2336 oh I’m in Texas and I like digging artifacst

It might come in handy someday.

becse i am told you too

I don't really know i have to be here from school lol

Yea inteligent humanoid entities have existed for a long time

Rocks are awesome. Some rocks can be turned into super strong alloys by processing the ores in them. I used to spend a lot of times studying rocks where I was a teenager. People from the village thought I was crazy.

Same

sameeeeeeeeeeeee

Same here

I am waussup

I’m from Ms. Garanes’s social studies, but hi

Wot school you talkin about,.l?

ChocoLiLi oh it’s a completely different school, 122

I’m here cuz another vid did this but he bled and I hate blood.

I think she isnt here

Lol imagine not hearing dr stone 5billion times a day

That’s 10billion percent right

imagine not knowing what dr stone is

@@mythicmars One of my fav anime’s

Ben Foong same

@steveXracer You clearly do not know what the definition of a scientific theory is. A scientific theory is as close to 100% scientific fact as one can get in science. I"m not going to argue the theory of evolution with a creationist, because that's a battle that can't be won. A creationist is a creationist, and no amount of scientific theory is going to change their mind because their beliefs are their beliefs, and they are as entitled to them as I am to entitled to my own. However, you are mistaking a scientific hypothesis for scientific theory.. It is a common misunderstanding. To say that evolution is the belief that everything came from nothing, just shows a very shallow understanding of the theory.

@steveXracer the big bang

steveXracer Steve is a troll. He doesn’t really believe in anything because he doesn’t really give much thought to anything, beyond tormenting people and tricking them into having arguments with him.

museum guy daaaaaaaaamm

Carbon dating the blood from your fingers.

I'm sure weathering has occurred at least to some point

If you make them you can tell , if you strike it with copper it will cold weild some into the surface of the stone. Also art was a ritual ,very often , everyone did it the same way , one style per tribe , you could try. Fake , I wouldn't ...

Carbon dating is a way and weathering can be done artificially

They'd put it next to their old specimen found in your area and then confirm if it is knapped the same/similair, then some other mumbo jumbo tech-magic they will be able to dicern how old the knapping surfaces are.

hmmmm you in Ms. Miles' class?

OHH MAH GAWD, ADA! ITS MEH EMILY

And no, I'm in Ms. Coreas Class, 6th grade

Bish plz

flint is found in chalk Chert is found in limestone or sandstone Flint and chert are almost identical.

I don't now

Most likely flint.

Try other types of stone be suprised

You plop a sufficiently large group of humans down in a new environment and you’ll soon have a smaller group that has gained the ability to survive in that environment. It’s not down to individual smarts. It’s learning from mistakes, yours and others. The fewer people you start with, the fewer mistakes you can make and have the group survive. So the person or people living comfortable a thousand years ago had previous generations to thank for figuring out what to eat and what not to eat. I think of that Into The Wild Guy who died from eating wild potato seeds (poisonous) and then starving because he was so sick from the seeds. Some criticize him for going out into the wilderness without sufficient knowledge and experience, but I think his mistake was going alone, as a group of one. If he had made a couple thousand clones, he could have learned what was safe to eat and what was not by trial and error testing.

Absolutely! Scalpels made from obsidian flakes are made to this day. They are the sharpest cutting material known to mankind, and are 100s of times sharper than the best metal scalpels. They are quite expensive and are used primarily by plastique/cosmetic surgeons as the incisions are very thin and heal much faster with less infection and scarring.
