Totallycasual
Why the fuck would your friend hit rebar with a $1000+ katana? Is he special?

rebar killed his family, he wanted justice in style
Ahhhh, now that's a hell of an origin story.
He did WHAT?!
godofhorizons
The Japanese didn't take good metal and make it great, they took shitty metal and made it good
pacobedejo
Made it serviceable...
They made some pretty decent equipment out of their shitty materials; ingenuity helped offset quality, but didn't make a superior piece

Water is not wet. In order to call something wet it needs to be soaked in water. You can not soak water in water.
visioneightfold
you can soak your logs in wood, you can soak your water in hydrogen dioxide.
AncientPostNecromancer
Hydrogen dioxide is highly explosive and unstable.
Indeed, be careful, Hydrogen Dioxide is found in tap water across the US! Some say that even our oceans could be contaminated with it.
Stenledsen
Why are we not using bullets made out of steel?
tastynachosaremything
I'm sure it has to do with the fact that lead bullets can mushroom and break up on impact, causing more damage. Steel would go straight thru
tehguldincalk
To expensive, steel is better used elsewhere. Although, the Russians do use steel for their cases
IllCaesar
Some bullets are. They're generally less effective and more costly than lead, though.
Burke616
Another part of it is mass. A bullet-sized piece of steel has less mass, thus imparts less force on impact, than a same-sized piece of lead.
F=mv^2. A bullet with less mass but the same amount of powder would go faster. Velocity is squared in the equation, so lower mass but higher
velocity would have more force.
You're right, I'm mistaken.
batosai33
Mainly density. Hollow points mushroom causing more internal damage and stopping in the body preventing collateral. 1/2…
ProxyPlayerHD
use Uranium bullets. even more dense!
Lambast
And they're self sharpening.
Full metal jacket on the other hand do not mushroom and penetrate, but have a lead core for higher Mass so more energy is carried. 2/3
Full metal jackets are used in war because of the genieva convention (I think). They cause less suffering, whereas cops hate collateral.
Near close, better summary
cowpiefatty
Man you should be a news anchor you got that shit out there faster than any news outlet ive heard of.

Also, water is wet
Ccnati
Right?! The impressive thing is a blade that still holds an edge. Any steel will split the bullet, but may not be useful after.
KNSKumo
Edge? Is a butter knife, it has no edge!
That’s what I’m saying. Obviously any thin steel will split it. But a good knife will split it and still have a sharp cutting edge.
Shovi
A knife with no edge? Oh that's so edgy...

yes, and when the bullet is made of soft lead higher velocity means less time to split and more stress on edge.

Lead is still the most common, though other materials are used for specialized application.
There is research in non lead bullets because lead is a problem at shooting ranges, but it's no ubiquitous yet, let alone decades ago.

No... Bullets are made of lead. They might have jackets on them but they are lead

Abracanawbra
Show me a video of a katana cutting a butterknife in half.
Necrothean
https://youtu.be/RyO46RQhYkQ Closest I could find is modern katana cutting pipe and steel plate.
That plate cut slow-mo is pretty impressive. It looked more like aluminum but I won't pretend to know that. +1 do recommend.
TheNLK
more importantly it was .4mm thick... could probably have cut through that with a heavy machete.
HatredandVitriol
Modern metallurgy can make SINGLE CRYSTAL METALS, we no longer need to fold different quality steel to make a usable item.
RealScienceMan
They mostly needed to do it because they didn't have enough iron to do the superior refining techniques Europeans did.
That and also the revisionist history of the nobles when swords were outlawed for commoners.
A sheet metal knife, with the correct composition, is vastly superior to anything ancients could even dream of making.
We can, could, since late 1800, forge steel with composition down to the correct molar concentration.
Iagainsti120
What about Ulfberht swords that used curcible steal with almost 0 impurities made around 9th to 11th centuries.
BEELZEB0B

Waaah your telling that as a knowledge of metallurgy increased and came up with better technique we make better blades, interesting

What are the desirable qualities of SINGLE CRYSTAL METALS?
JayEnfield
It's kind of like single malt scotch. But metal.
Weakness in metal is largely due to connections between small metal crystals, single crystal, no weakness.
A cracker without the hole punched through the middle, if you will.
TinyRocktopus
True but it is strong in one direction, it's not isotropic, so it's only used in specific applications (turbine blades)

The entire reason they were folding metals in the first place is because their steel is shit. Europeans knew that technique too, but

Basically, they made terrible steel that fractured if you looked at it the wrong way. Traditionally you have to spend 7 years of training1/2

I'm not sure I'll ever find it again, but there was an article on how China has to import the ball bearings for pens because they just>>

Modern processes eliminate the differences.
You’d think, but compare stainless steel from either country and you’ll realise which lasts longer, which breaks, which rusts first.
That's process quality control, not materials.
Raptor65
Not so much that the steel was shit, that's just how you make homogeneous steel pre-industrial revolution, like kneading dough to make bread
...No. Crucible steel's been around since the medieval ages and that was GOOD stuff even by modern standards
The japanese didn't have crucible steel for a long time though, and so folded the semi-molten metal to remove most of the impurities
This is what I meant, if you have dirty steel you fold and weld to remove inclusions and homogenize it. Lot to explain in 140 characters.
It's why a Katana is made of three layers, you have the hard steel edge (made from pig iron pre-folding)
A softer steel backing, and then an iron core. Fun fact but you lose steel purity from the heat as the carbon burns out of the metal
progressed past it as the quality of their steel increased.
eggmuffin
It was the mid-medieval profusion of Toledo steel that took most folding out of the equation.
LusciousLucius
Their IRON was shit. Their steel was honestly pretty good considering how low-carbon all their iron was.
vindik8or
Iron is iron. Their ORE is shit (low yield), takes a lot of extra processing to get raw metal.
Iron is not just iron. It exists in different oxidation states, crystal formations, purities, and carbon content. Ore is just a part of it.
SlightlyRelatedToThePost
Semantics. Iron is iron, if it's oxidized, impure, etc. it's not iron. It's iron+other shit. Japan had lots of crap ore with low iron.
The first three things are reasons for needing to process it. The fourth thing is the aim of all that processing - steel.
