You don't sharpen obsidian, it breaks and then becomes sharp. It's a crystalline structure, like you said volcanic glass. You hit someone with obsidian, it breaks and embeds pieces into them and makes the blade sharper. It doesn't hold an edge because it's very brittle.
@@ooktube yes it would be just as sharp as any other knife but it’s the fact that you have a knife made of obsidian that isn’t crude like normal obsidian blades.

@@ohioknifelover Sort of, in that the chipping can be microscopic. This just results in faster sharpness degredation. You can grind obsidian to a point if you're careful, but it does not hold a razors edge for as long as a metal one would. There is actually a much easier method of producing extremely sharp obsidian blades, although they still don't hold an edge for a long time, and unlike metal they can never be returned to full sharpness. In Mesoamerica, many of the indigenous civs had prismatic blade manufacturing industries. They would prepare an obsidian "core" and pry off blades that had a characteristic trapezoidal shape in cross section. They're basically flakes with a specific shape. I would highly recommend looking up TH-cam videos of the process, it's very interesting. These were essentially the disposable razors of their day and had the advantage of being much sharper than flaked edges. Sharper than modern razors at times. But of course they chipped microscopically and the edge did not hold long. But since they could be produced easily and in bulk they were common.

If you understand WHY obsidian is so sharp, you'd understand that you can't possibly create such an edge by normal means of sharpening. Hope that cleared some stuff up for some.
Chipping an obsidian will always result in the sharpest edge from any kind of method. It results in atomic scaled edge, which is the sharpest physical edge you can get
When I was in college I took geology and the teacher was crazy. In a John Hammond way but for rocks. He wore Hawaiian shirts, cargo shorts, and sandals no matter the weather. He told us a story about a geologist he knew who had to go in for surgery. The guy made his own obsidian tipped scalpels for the doctors to use on him. (They are now available commercially in limited supply.) His incisions healed so cleanly the doctors couldn't even find the exact spot they cut.
Damn that's insane, I guess the teacher was a very interesting person... That's a good thought spark though, as linen helps injuries to heal faster, perhaps those scalpels had some similarities with this
@@yellowgrumpydog5528 im guessing they healed faster because obsidian scalpel would be mad sharp like way sharper even then normal scalpel so its easier to heal for our body ?
are you saying that your teacher attempted to create an amusement park with replicated prehistoric rocks that he manufactured using the remnants of fossilized minerals combined with modern types of rock?
@@tymekfigua6757 makes sense, but by linen I'm referring to the elettromagnetic properties of that fabric, meaning that those electrons captured by the fabric from the magnetic fields coming from the environment and the body, gets in a way "harmonised" because of the atomical composition of the linen fabric, so it appears that this specific electric attunement has this healing effect on wounds... In fact linen was used in hospitals a while ago as they observed faster healing when the patients got wrapped with this fabric. That's why I was wondering, if the obsidian blade has the same nature? Perhaps when the obsidian blades cuts the flesh something similar could be happening on an atomical level, allowing a more gentle separation between the molecules of the skin and flesh
@@yellowgrumpydog5528 a sharp piece of obsidian is capable of actually cutting cells in half. A typical steel blade only rips the cells in half. So it actually makes perfect sense that an incision from an obsidian blade would heal entirely without scarring and potentially even heal faster.
Man there is a reason why obsidian is used in some surgeries. It's extremely sharp and if sharpened in very specific ways it can be sharper than any metal knife.
Obsidian isn't meant to have an edge and on top of that, it's not "dull". Obsidian is incredibly sharp when it breaks and that's the idea behind the knife. When you hit someone, it breaks, shatters volcanic glass into them and simultaneously makes the knife much sharper. Great knives and even more impressive that ancient people saw the amazing potential behind obsidian. Time for the obligatory "I didn't mean to start a war in the comments 💀" edit
Lol, when it breaks, it's going to be no bigger than a pocket knife. So much for your...."sharper knife." Obsidian is better used as arrowheads. Then your shrapnel idea works if your opponent has no armor. Even better for hunting.
@@BrentMalice I mean, yeah. The fact that ancient people found so many uses for things doesn't impress you? Let me take away your phone, your computer, your books (even though I highly doubt you have any) and any current knowledge you have right now and let's see how well you fair in ancient times?
The only way to sharpen obsidian is through a process called pressure flaking, where pressure is applied to the thin/blade points of the blade until they flake off, resulting in a sharper blade. Although obsidian is sharper, an easier to find stone, that is also more durable than obsidian is flint, which is what many people use instead.
@@sethmp333his method of sharpening was very inefficient and only increases the sharpness by a small margin, because the sharpness of obsidian is famous due to the fact that the flakes break off and naturally form an edge. Also due to the irregularities in the widths and sharpness of the individual teeth, a sharpener like this should only be used on a straight blade and not one with teeth. In fact, he was lucky that he did not damage his blade.

Lets put it this way: as we know glass is brittle, so it doesnt have an edge. When it breaks, even if its barely touched, the person is easily cut from the glass. Same thing with obsidian. Except its way sharper.
In water, glass tends to react much better to sudden changes in its shape, size, or whatever else you wanna use to describe it. You can drill a hole in a glass window if it’s submerged but if it’s above water, the glass will shatter all the way throughout the window.
@@TheStarkman123 honestly, I’m not sure. I’ve only ever seen videos about it but not why it happens. I assume that the water has higher pressure than the crack forming so it just doesn’t. But that’s my ASSUMPTION^ I’m sure there’s more to it than that. Maybe the water cancels out the force. I would love an answer tho.
Kind of... it has to do with the energy dissipation. When you crack glass in air the energy is almost entirely dissipated through the glass, a little in the air. Water is 800 x more dense so as you can imagine it will absorb much more energy.
I believe it mostly to do with heat dissipation. Adam Savage talked about one job where he had to drill through several glass bottle and he had to keep a steady stream of water on it to work. But I've never had to work with glass like that so ..
As a professional miner, I can confirm the only way to preserve the obsidian and it’s integrity is through the use of diamonds to sharpen it Source: trust me bro
Breaking it is the you have no tools but rocks to chip the gkass/obsidian method of sharpening or you sand it down with a modern harder material for a far better far more consistent sharper edge.
@@airgliderzno obsidian is sharp when it gets broken. The whole reason obsidian is so sharp is that it breaks down to such a small level. That it makes any broken piece of obsidian incredibly sharp.
@@airgliderz no. Sharpening with a harder material will dull it. A flake of obsidian is sharp because of how the material breaks, grinding it down will only ruin that edge.
@@crabwithknife wrong i, honing is no different then chipping a chunk off chips, honing is far more controlled making a finer straightener more constantly sharp edge. You must know nothing about glass or obsidian both of which can be honed far sharper far more constant sharp edge then by p RT inactive cave man like chipping with rock. Technology improved the edge on obsidian glass. In fact we can probably grow a far more consistent pure more durable obsidian crystal than mother nature con.
In the 16th century Germany there were hurlbats which essentially are throwing axes with more points and also throwing crosses. Both were said to be used by german knights. We also have a written account of a German 16th century student who beat his teacher to death with a throwing cross. Afterwhich they were banned in some parts of the holy Roman empire (now Germany) which might indicate some use by people.
Old knives crafted with obsidian or flint weren’t sharp because they grounded them, it’s because they would break the edge at a specific angle which would create a sharp edge
How can you tell that you are not Mexican? If you weren't a gringo, you would know that obsidian is quite fragile, so much so that the Aztecs carried extra blades to replace the ones that broke from their makahutl. Since when they hit bone they broke, that's why they held their wooden and obsidian weapons, not like the shitty ones they tried to sharpen.
In fact the makahutl was not the only weapon of its type since there was a larger version called makahutole. But that one, being so heavy, didn't let you carry a shield.
You're supposed to knap the edge with a rock or other rounded blunt tool. When you knap the edge, you're chipping small pieces off, that makes the edge sharper because that's how Obsidian is structured.
I think its pretty obvious he is trying to force it into a normal blade, that is the challenge its quite clear if he wanted a serrated knife, he would not have done this this is very clear is this clear?
Minning engineer here You can get a better edge on obsidian by breaking it than grinding it (have in mind that either method wontlast long as it's a brittle material) And please make sure to have proper safety precautions when grinding it as it's an abrasive material so it's dust can irritate eyes and skin quite badly and it's kinda hard to remove from surfaces like wood as it isn't water soluble, also make sure to wear at least a face mask if you work constantly with it because aside from the irritation, the accumulation of it in the lung may cause Silicosis also known as minner disease
Yeah but if he actually knapped the blade, the way it's supposed to be done, he wouldn't be able to advertise his product. Gotta get that bag bro, nevermind that a work of art gets destroyed along the way
@@tumblerusa bro literally every single suggestion in the comments is telling you to knap the blade like obsidian should be worked. Don't even try to sit there and say your sharpener was "highly requested" 💀 if you're advertising a product just own it, you'll get more respect, even if this blade material was a terrible choice for the sharpening method. Consumers these days value honesty and integrity more than just about anything, especially in the outdoors market 👍

Obsidian is sharp because of the way it fractures during the making process, you can’t sharpen it with abrasive material, all that does is cut open your lungs when you breath in microscopic fragments of super sharp rock
You sharpen high-silica stone blades through pressure flaking, or chipping of flakes near the edge. In order for the blade to be as sharp as possible, some serration is required.

so if i remember correctly, broken glass can be one of the sharpest possible structures because when it breaks, the edge can be as thin as one particle, but to sharpen that specific knife you would want to first sand it down using a belt sander, then go with the grind stone. glass can work well as an arrow head given you don't want to reuse it.
Keep going, that knife was knapped. You can sand glass smooth. People break glass bottles to make cups all the time. Bring that sucker to a fine edge!!!!
You need to sharpen the glass with a rotating grinding wheel that is water safe. You can clearly sharpen it like a knife once the glass is submerged in a tank of water. Otherwise it chips and breaks. The water changes the vibrations and nullifies the standard above water break.
as an explanation: Glass type materials when submerged are more resilient to stress without shattering because of the higher viscosity of the environment it is in. Higher viscosity means higher kinetic dissipation, which implies higher vibrational dissipation, so the material vibrates for less time when struck. Since glass type materials shatter easily due to vibrations, when submerged in water, obsidian doesnt shatter as easily, so it can be sharpened somewhat easier
No. Obsidian is knapped, not grinded. The knapping shapes the edge along natural occuring strenght lines. A grinded and linear edge will break on first use. Cave men knew it better
@@robertrosen2703 if you knew anything about physics, you would not have put that reply, and after mine. The water will absorb all of the vibrations. Vibrations are what makes glass break.
@iron0xide974 you were so proud of your explanation that seeing anyone not agreeing with you was taken as an opposing thought. @robertrosen2703 is stating a proven way of sharpening obsidian that doesn't involve a viscious environment. He didn't say it wasn't possible; rather, he stated it isn't as durable as the readily known knapping technique pioneered before science was science

Diamond plated disc? No shit he learnt that in Minecraft 💀
Jokes aside diamond is actually used in a lot of strong stuff
For sharpening purposes on overly dull blades Diamond Plates are better than normal Whetstones. Less prep time, costs less, and can get a lower grit so you can reshape the edge. Diamond is just a good material when it's used as small pieces like drill points or dust.
He ain't the first person to use if for sharpening, he just made a easy way for people to sharpen knives who don't have the skills to use a normal whetstone.
Hope this has been a interesting read.
Fun fact: obsidian is sharper than surgical steel and can actually get up to 1 atom thin at its sharpest point
How
It is one of the few materials on earth that can cut through a cell instead of crushing it.
@@Chickenuggeter in order to sharpen obsidian, need to break away chunks of it to reveal its edge. trying to sharpen it with a whetstone won’t work.
It’s not exactly 1 atom, but it can theoretically get there with a good break
No it can't Maybe you're talking about the tongstein nanoneedle
Haven't we already told this dude you don't sharpen it to get it sharp, you break it
If you understand WHY obsidian is so sharp, you'd understand that you can't possibly create such an edge by normal means of sharpening. Hope that cleared some stuff up for some.

I love this kind of content. This video gave me splinters
When I was in college I took geology and the teacher was crazy. In a John Hammond way but for rocks. He wore Hawaiian shirts, cargo shorts, and sandals no matter the weather. He told us a story about a geologist he knew who had to go in for surgery. The guy made his own obsidian tipped scalpels for the doctors to use on him. (They are now available commercially in limited supply.) His incisions healed so cleanly the doctors couldn't even find the exact spot they cut.
Damn that's insane, I guess the teacher was a very interesting person... That's a good thought spark though, as linen helps injuries to heal faster, perhaps those scalpels had some similarities with this
@@yellowgrumpydog5528 im guessing they healed faster because obsidian scalpel would be mad sharp like way sharper even then normal scalpel so its easier to heal for our body ?
are you saying that your teacher attempted to create an amusement park with replicated prehistoric rocks that he manufactured using the remnants of fossilized minerals combined with modern types of rock?
@@tymekfigua6757 makes sense, but by linen I'm referring to the elettromagnetic properties of that fabric, meaning that those electrons captured by the fabric from the magnetic fields coming from the environment and the body, gets in a way "harmonised" because of the atomical composition of the linen fabric, so it appears that this specific electric attunement has this healing effect on wounds... In fact linen was used in hospitals a while ago as they observed faster healing when the patients got wrapped with this fabric. That's why I was wondering, if the obsidian blade has the same nature? Perhaps when the obsidian blades cuts the flesh something similar could be happening on an atomical level, allowing a more gentle separation between the molecules of the skin and flesh
@@yellowgrumpydog5528 a sharp piece of obsidian is capable of actually cutting cells in half. A typical steel blade only rips the cells in half.
So it actually makes perfect sense that an incision from an obsidian blade would heal entirely without scarring and potentially even heal faster.

Obsidian isn't meant to have an edge and on top of that, it's not "dull". Obsidian is incredibly sharp when it breaks and that's the idea behind the knife. When you hit someone, it breaks, shatters volcanic glass into them and simultaneously makes the knife much sharper. Great knives and even more impressive that ancient people saw the amazing potential behind obsidian.
Time for the obligatory "I didn't mean to start a war in the comments 💀" edit
But can you use it in kitchen without breaking it?
its amazing that people found a use for a sharp thing?
Lol, when it breaks, it's going to be no bigger than a pocket knife. So much for your...."sharper knife." Obsidian is better used as arrowheads. Then your shrapnel idea works if your opponent has no armor. Even better for hunting.

At least this is where I first saw and learned the word pneumonoultramicroscopicsilicovolcanoconiosis, thank chat.
The only way to sharpen obsidian is through a process called pressure flaking, where pressure is applied to the thin/blade points of the blade until they flake off, resulting in a sharper blade. Although obsidian is sharper, an easier to find stone, that is also more durable than obsidian is flint, which is what many people use instead.
He literally just sharpened obsidian not your way. So maybe edit your comment to not say “the only way”
@@sethmp333his method of sharpening was very inefficient and only increases the sharpness by a small margin, because the sharpness of obsidian is famous due to the fact that the flakes break off and naturally form an edge. Also due to the irregularities in the widths and sharpness of the individual teeth, a sharpener like this should only be used on a straight blade and not one with teeth. In fact, he was lucky that he did not damage his blade.

In water, glass tends to react much better to sudden changes in its shape, size, or whatever else you wanna use to describe it. You can drill a hole in a glass window if it’s submerged but if it’s above water, the glass will shatter all the way throughout the window.
Does it have anything to do with the water pressure holding the glass together / absorbing the vibrations of the drill?
@@TheStarkman123 honestly, I’m not sure. I’ve only ever seen videos about it but not why it happens. I assume that the water has higher pressure than the crack forming so it just doesn’t. But that’s my ASSUMPTION^ I’m sure there’s more to it than that. Maybe the water cancels out the force. I would love an answer tho.
yeah i was thinking the same thing, it might have a sharper outcome used on a whetstone
Kind of... it has to do with the energy dissipation. When you crack glass in air the energy is almost entirely dissipated through the glass, a little in the air. Water is 800 x more dense so as you can imagine it will absorb much more energy.
I believe it mostly to do with heat dissipation. Adam Savage talked about one job where he had to drill through several glass bottle and he had to keep a steady stream of water on it to work. But I've never had to work with glass like that so ..
As a professional miner, I can confirm the only way to preserve the obsidian and it’s integrity is through the use of diamonds to sharpen it

You don't sharpen obsidian. You break it.
Breaking it is the you have no tools but rocks to chip the gkass/obsidian method of sharpening or you sand it down with a modern harder material for a far better far more consistent sharper edge.
@@airgliderzno obsidian is sharp when it gets broken. The whole reason obsidian is so sharp is that it breaks down to such a small level. That it makes any broken piece of obsidian incredibly sharp.
@@whitenobeard yes it is by sharpening or primitive breaking.
@@airgliderz no. Sharpening with a harder material will dull it. A flake of obsidian is sharp because of how the material breaks, grinding it down will only ruin that edge.
@@crabwithknife wrong i, honing is no different then chipping a chunk off chips, honing is far more controlled making a finer straightener more constantly sharp edge. You must know nothing about glass or obsidian both of which can be honed far sharper far more constant sharp edge then by p RT inactive cave man like chipping with rock. Technology improved the edge on obsidian glass. In fact we can probably grow a far more consistent pure more durable obsidian crystal than mother nature con.

Afterwhich they were banned in some parts of the holy Roman empire (now Germany) which might indicate some use by people.

Damn, every day I feel that calling your people leaden heads rather than highlighting their problems sounds like a lake. 😐
How can you tell that you are not Mexican? If you weren't a gringo, you would know that obsidian is quite fragile, so much so that the Aztecs carried extra blades to replace the ones that broke from their makahutl. Since when they hit bone they broke, that's why they held their wooden and obsidian weapons, not like the shitty ones they tried to sharpen.
In fact the makahutl was not the only weapon of its type since there was a larger version called makahutole. But that one, being so heavy, didn't let you carry a shield.

@@AngelCod-jh2qb wtf did you just yap about
You gotta knap it. Forms razor edges. Can be done with other rocks, but obsidian knapping forms edges that can be on the nano scale in sharpness.
Obsidian is the sharpest material on earth
Obsidian scalpel can be cut that are so precise that they Tio several times faster than steel scalpels
You're supposed to knap the edge with a rock or other rounded blunt tool. When you knap the edge, you're chipping small pieces off, that makes the edge sharper because that's how Obsidian is structured.

You can get a better edge on obsidian by breaking it than grinding it (have in mind that either method wontlast long as it's a brittle material)
And please make sure to have proper safety precautions when grinding it as it's an abrasive material so it's dust can irritate eyes and skin quite badly and it's kinda hard to remove from surfaces like wood as it isn't water soluble, also make sure to wear at least a face mask if you work constantly with it because aside from the irritation, the accumulation of it in the lung may cause Silicosis also known as minner disease

thats not how that works.
Obsidian is sharp because of the way it fractures during the making process, you can’t sharpen it with abrasive material, all that does is cut open your lungs when you breath in microscopic fragments of super sharp rock
But as it is volcanic glass, it’s very fragile, and isn’t well-suited for use as a weapon.
And then you hit them with the wooden baseball bat
Which you had in your other hand, which geologists can't see, due to them only being able to see rocks and minerals.
You should try that under water. It should result in cleaner/sharper edges with less risk of unwanted shattering.
And less obsidian dust in his lungs
You sharpen high-silica stone blades through pressure flaking, or chipping of flakes near the edge. In order for the blade to be as sharp as possible, some serration is required.

You need to get it super sharp
so if i remember correctly, broken glass can be one of the sharpest possible structures because when it breaks, the edge can be as thin as one particle, but to sharpen that specific knife you would want to first sand it down using a belt sander, then go with the grind stone.
glass can work well as an arrow head given you don't want to reuse it.
Obsidian can’t be sharpened. You need a rounded small blunt object or tool to chop it. After that… don’t touch it

@@DrBright5558 if you break it its sharper than 3 kitchen knifes combined
Underrated TH-camr
You need to sharpen the glass with a rotating grinding wheel that is water safe. You can clearly sharpen it like a knife once the glass is submerged in a tank of water. Otherwise it chips and breaks. The water changes the vibrations and nullifies the standard above water break.
as an explanation: Glass type materials when submerged are more resilient to stress without shattering because of the higher viscosity of the environment it is in. Higher viscosity means higher kinetic dissipation, which implies higher vibrational dissipation, so the material vibrates for less time when struck. Since glass type materials shatter easily due to vibrations, when submerged in water, obsidian doesnt shatter as easily, so it can be sharpened somewhat easier
@@falkez1514 my point exactly
No. Obsidian is knapped, not grinded. The knapping shapes the edge along natural occuring strenght lines. A grinded and linear edge will break on first use. Cave men knew it better
@@robertrosen2703 if you knew anything about physics, you would not have put that reply, and after mine. The water will absorb all of the vibrations. Vibrations are what makes glass break.
@iron0xide974 you were so proud of your explanation that seeing anyone not agreeing with you was taken as an opposing thought. @robertrosen2703 is stating a proven way of sharpening obsidian that doesn't involve a viscious environment. He didn't say it wasn't possible; rather, he stated it isn't as durable as the readily known knapping technique pioneered before science was science
