You are not understanding. It took on its hardness, Domu is as hard as diamonds. But its chemical composition is not that of a diamond. Domu is hard as diamond human skin.
Just like you still haven't learned a jabroni from starting of shippuden is a peasent in front of war arc Sakura and War arc Gaara.It's because we've had this argument hundreds of times, and you've yet to learn that Kakuzu > Sakura, and Tsunade. We're tired frankly.
You can't smash diamond hardness. Diamonds are smashable because of completely different properties/elements. Toughness =/= hardness. You can smash a diamond because of it's toughness. You can't smash it's hardness. Domu = hardness of a diamond =/= toughness of a diamond that allows you to smash a diamond.
So no. It doesn't work like that. Not only Domu actually becomes a diamond with all it's properties aside from the already existant hardness.
No Diamonds can be smashed no matter what. You however cannot cut a diamond without another diamond.
Domu is still human skin at the end of the day, which has became as hard as diamond using the earth release. Since its the earth release raiton cuts into it.
That is ONLY possible because the element of toughness exists in it. If the element of toughness does not exist and you have only the element of hardness, you cannot smash it. Toughness is what allows you to smash a diamond and realistically speaking, diamonds can't lack the element of toughness so you can smash it regardless, but Domu only has the property of it's hardness. You cannot actually smash diamond hardness if the element of toughness does not exist.
I know. Don't mistake me for a Kakuzu fan or anything. I'm just saying you cannot crush something as hard as a diamond if it doesn't actually contain it's other properties. And that's only possible in fiction.
Yea, because Raikage isn't superman, for him to have an anti-kunai body he needs the lightning armor. duhr duhr.

Raikage's body is what's super durable. Lightning armour only enhances his durability, and we've already seen lightning armour get pierced by chidori.

I'm a novice on this Domu stuff, but if Diamonds are so easily smashed and whatnot, shouldn't Chouji's rolling boulder have crushed it with ease or at least damage him? I'm not sure you can apply these real life facts here.
Of course you cant. But to say his domu will protect against all physical attacks when it only survived against Chouji's technique is ridiculous and means it flies under the no limits fallacy. Tsunade and Sakura have the power to bust open Susano unless domu has shown to do the same they smash through it.
Domu is not suggested to act like a diamond in the legitimate translations of the databook. It merely says "A body like diamond, repelling everything!!" to begin with, as in a subtitle. Hyperbole is all there is to this part, as it clearly isn't supposed to 'repel everything' and is contradicted later on in the actual explanation of the entry.
"With the chakra flowing through all parts of one's body, the skin is hardened, increasing its defence power to its utmost limits." The skin is merely hardened tremendously through chakra to the point where it's no longer possible to harden it anymore. It then says "The amount of techniques that can break through the areas hardened by the "Earth Spear" are close to zero, not including its undeniable weak point: "Lightning Release Ninjutsu"." This contradicts the "diamond morph" hyperbole part of it as it suggests it doesn't actually 'repel everything' but has a weakness to lightning and can be penetrated by almost no jutsu. This leaves room for jutsu's like TBB and the like, making this entry very unbiased. It's chemical composition is nothing like diamond. It's no Diamond morph, it's real name is Earth Spear. Only wankers try to call it diamond.
Shikamaru compares his body to Steel [You must be registered for see links], but we all know its ability to stop Chouji's attacks and a point blank explosion puts it far above steel. Same applies to Sandaime Raikage, whose body was compared with Steel. So either NV steel is OP or steel is used to convey the greatest levels of defence. In the same scan however, he suggests no physical attack can harm him. This is being claimed by the very person whose lived many hundreds of years and has surely seen strength on the level of Tsunade's before. He fought with Hashirama himself who probably had superior strength if anything. He knew of the Gin and Kin brothers as shown when he was revived, two people whose v2 forms hold immense strength, yet he still made this claim. I don't see much reason to doubt it, given the fact the Databook and the manga both agree in this concept.
Your claims are ridiculous and all speculation.
Sakura survive point blank explosions from many kunai.
Those weapons are metals, they arent steel.
Hashirama has never shown to have above average strength. To say Kakuzu has dealt with someone with Tsunade's strength is speculation.
If you believe his body is like steel, then you must believe his blood is like iron?
I never denied he had durable skin, but to assume his normal skin is immune to kunais, is to say he is superman and cannot be pierced by needles and etc needed for medical purposes either.. but of course thats not correct either now is it?
Rasenshuriken something superior to the wind cast net imo took out the armor , and scratched the skin.. the wind cast net sliced him up when he had no armor on.
So again, bro... he needs the armor to tank a kunai or a sword ... Non-piercing techniques he might be able to tank like fireball jutsu or water dragon and etc .. but actual kunais and swords? he ain't tanking without an armor. And we already know that a kunai can't do much against the lightning armor .
How so? They are supported by databook and manga. Don't see why everyone always chooses to disregard anything that didn't happen directly.
Good for Sakura.
Which weapons, you failed to clarify.
I didn't say he has. He still knew Gin and Kin and claimed he was immune to physical attacks. Databook and Kakuzu's statement agree with one another. There's literally no reason to believe he cannot survive her attack. Everyone always denying databook facts because they can't differentiate between apparent hyperbole and fact/explanation.
