Just a heads up. Obsidian while sharper than any solid bladed object, can leave shards in whatever is cut. Think of it like a grill brush. All it takes is one little wire or shard.. be safe!
Fun fact: Obsidian was a candidate to replace stainless steel for surgical scalpels, as the sharpness made incredibly clean incisions with much less resultant scarring, however was rejected for that exact reason - the brittleness of obsidian posed a high risk of leaving shards behind that could cause serious internal bleeding post-surgery
@@Ankh_The_Artist No, Brain rot comes from different things, maybe associated with games but not from games. What do I mean ? The Twitter people that complain about games when they don't even play them, that's brain rot, when you are exposed to too much stupidity. This comment of mine is just a meme I remember from years ago, I get what you're saying but my opinion is that video games do not rot our brains, it's moronic people (in Twitter) and anywhere really
@@mccoolfriend6818 I'm talking about the slackjaw losers who go "oh muh gah Minecraft????" Whenever someone mentions something that is in Minecraft. I saw a video about a cave and the top comment was saying it was literally just a ravine from Minecraft. There are comments on videos like these where people are genuinely confused how he breaks the obsidian. There's a difference between being reminded of something and referencing it, and being so braindead that you genuinely believe that these real world things are from Minecraft.
This has always confused me. Theoretically, everything could get to the point where the edge is thin enough to cut through the individual organic cells of a thing, which is what makes something sharp. The main issue being whether or not the blade is durable enough to do so.
What is the technique called how he shapes the obsidian and what’s the physics behind it? It’s so cool how he applies the pressure to form the blade in a precise matter!
Imagine all of the beautiful gemstone he has wasted to learn how to make a knife. He wastes so much gemstone even making this one knife that would be a hell of a lot stronger if made from metal or hard rock. Also a blade made from obsidian is not very safe as it will leave tiny shards in the food. I would much rather have a huge size raw piece of obsidian than that knife.
The difficulty of this pressure flaking and knapping is absurdly high. I've only ever made arrow heads from Obsidian and my hands and knees hated me afterwards so major major props to you and your friend for receiving such a great gift.
None of my friends have ever made me an obsidian knife, and now I'm considering getting new friends. In exchange, I can provide playful banter and never let your accomplishments go unnoticed.
Man now I want you as a friend 🤩 in exchange I can offer a friend that's fine if we only speak a few times a year, but when we do I'll hype up everything you do. I also am able to offer dark humor mixed with sarcastic optimism
I can tell you from experience, as I've made many obsidian knives, you don't want to use obsidian on food. Obsidian shard were looked into for use in surgery, because of how insanely sharp it is. But was quickly rejected, not because it didn't work, it absolutely did, but because obsidian has a property that causes tiny flaked to break off when cutting flesh and other soft,yet firm things. Fish for example. So if you do this, you will have small shards of obsidian in your food. The sharper the obsidian is, the more shards there will be.
BTW can you tell me if blade like this one is actualy sharp? The edge of big singular flake looks sharp, but the finished knife looks more like a saw than a knife.
@piddlesfiddles2075 the serrated edges are the sharp bit. It's so thin that it'll self-sharpen as it chips over time. But the person's right, obsidian knives are not recommended to use. Great souvenirs though if you're a souvenir person
@@piddlesfiddles2075sharp like a steak knife for sure, but not for fileting a fish, the blades of a nahua macuahuitl would be much cleaner and better likely
@@piddlesfiddles2075thank you for asking this question I have the same thought every time I see this guys vids. They are cool knives but they don’t look like they would great for clean cuts
@@alishermannopov Diamond pickaxe bro. In Minecraft use a Diamond pickaxe to get it bro. But in the real Life use a fcking stone bro. I didnt say that obsidian is a Diamond bro
It's because this weapon was one of the first steps in humanity's long and bloody process of developing deadlier and deadlier tools. But it's also beautiful, because it shows how us humans can use our intelligence to enhance our abilities beyond what we evolved, using tools for good as well as bad.
It's a shame that most people don't understand just how much skill it takes to work with obsidian this well. Don't let these videos fool you. This is not that easy. The person making these is extremely skilled.
As someone who has worked with obsidian a lot making custom Macuahuitl’s and small knives as well you did a fantastic job my friend. Obsidian is an extremely hard material to work with and shape. Well done 👍🏽
@@nemasisdemarini8339 You also have to keep in mind that when the Spanish showed up, the Mayans thought the Spanish were gods with all their steel and whatnot
Some of the sharpest scalpels in the world are made of obsidian. They can be so sharp they can cut between individual cells. There won't be any shards in the fish unless he smashes it with a rock.
@@justinankarthey also use lab made diamond blades. They stay sharp for up to 50.entire surgeries! They're really cool, but obsidian might be sharper ... due to it creating this slivers and shards better than diamond would.... they use obsidian blades for eye surgeries and any surgeries where you have to leave minimal scaring
yeah no, obsidian is actually a very reliable material to make blades with, the only true reason that obsidian knives in a kitchen are unusual is because obsidian tools are way harder to mass produce than steel.
I don't think people get how incredibly hard it is to work with obsidian. Seeing that he has no cuts on his hands, he's clearly extremely skilled at his work.
@@o2Hayden He makes it look super easy, so people may underestimate its difficulty. They watch the video perhaps because they are fascinated by how the big chunk of obsidian at the start is turned into something elegant and beautiful by him.
@@oldbonniegamer938 You are probably right, but my point is that he has no visible cuts on his hands despite how wicked sharp the flakes of obsidian are.
It's really interesting to see someone create blades using the same technique used by early man. It really makes you appreciate the ingenuity of humankind even in the dawn of our existence. It also just results in a really badass knife.
fun fact about obsidian: It’s extremely felsic (high silica content) in composition, which is why when it fractures it has that conchoidal shape. Now most felsic rocks are usually light colored - but obsidian gets its black color from abundant, microscopic crystals of minerals like magnetite, hornblende, pyroxene, plagioclase and biotite (Gets whacked with a baseball bat that I didn’t see because as a geologist I can only observe rocks and minerals)
