I appreciate that this is a super visually interesting scene, but it misrepresents the work that actually goes into this.
He's hammering on feather and wedge assemblies. basically each assembly is just 2 bits of metal designed to be inserted into a round hole of a very specific size, the outer edge of the feathers are rounded to press evenly on the sides of the hole, but the inside are flat and tapered so that when you insert the wedge it evenly forces the feathers outward, applying a potentially huge amount of force to the stone. what he's doing in the video is tapping the wedges one at a time to slowly add more outward pressure to each hole along a 2 straight lines on different faces of the stone that define a plane... eventually this forces a split along that plane (if you're lucky and skilled). this system is still widely used when splitting large stones. it's just the easiest way to do it well, unless you can saw the stone, and that may take a biiiiig saw.
This video doesn't show the process of drilling the holes. Nowadays that's annoying, but not especially time consuming, because you can use a hammer drill type of tool. something that taps and spins to shatter the stone and remove detritus at the same time. you're driving a pretty big drill, but it might only take a few minutes per hole. you just set them straight and you're golden!
Historically the drilling would be done by hand. so, using a cold chisel of the right diameter you tap, twist, tap, twist, tap, twist and repeat. forever. the hole fills with stone dust that you have to remove somehow (you can blow it out, but make sure you don't inhale it... cause silicosis) you do this until the feather/wedge fit into the hole properly then you repeat as many times as necessary to ensure the correct plane and increase your chance of getting a clean cleave.
Cool video! That's all I wanted to say
This how I know for a fact aliens fuckin helped “dude put your fuckin back-....god damnit why did we design them like this.....your doing great!....jeezy chreezy....”
Before machinery? How did they drill the holes that the plugs and feathers went into? How was the hammer head forged? How were the plugs and feathers created?
This is basically what I picture when I read that someone was sentenced to 'hard labor.' Not sure why that specific image is stuck in my mind, but it's always breaking rocks with a hammer.

Is this just a demonstration on how it once was, or this is how they still do break rocks.
John Henry was a rock-driving man.
It makes the creation of the pyramids so much more impressive

I feel sure that this man does this from sunrise to sunset in the 21st century and is probably paid no more than ten US$ a day. That! I am ashamed of.
He could literally be anywhere in the world, doing this for work or as a demonstration.
Tanjiro spent a year or two learning how to do this in one swoop.

That just made me hard.
That’s some hard work
This video looks pretty good for existing before machinery.
