Adamantine

**Adamantine** is a unique artificial metal created by the metallurgical prowess of Read Kogane. An alloy forged from nearly forty different metals, and originally known as *Toughyrite*, this metal is near unbreakable and possesses numerous desirable properties. Capable of supporting immense weights and surviving temperatures well into the hundreds of thousands of degrees while also retaining numerous other beneficial chemical properties, adamantine would be the perfect building material in any situation except for two factors. One is the difficulty of working with the material. Due to the complex forging of the material, as well as how even the incomplete version quickly becomes near impossible to manipulate, let alone forge, Kogane alone has so far been able to produce anything with this material through thorough usage of her devil fruit. The second is the astronomical cost of production. Due to the labour-intensive construction by the Queen of Steelworks island itself, this material costs more per pound than the average marine battleship, coming it at 1,500,000,000 per pound.

According to its creator, Adamantine is the Strongest Metal in the World, surpassing any other material she is aware of by a large margin in terms of durability and hardness, even seastone.

## Appearance

Adamantine is known for being both incredibly smooth in appearance, as well as having a green colouration. Kogane has figured out how to colour it without ruining its properties, however.

## Additional Noted Properties

Beyond it's virtual indestructibility, Adamantine has several other properties that are extreme in nature. Due to its rigidity, it is incapable of absorbing shocks, instead perfectly transferring them through the material, leading most Adamantine items to be lined with shock absorbing materials.

It is also an extremely poor conductor of heat, taking hours for the standard forge to heat a piece even a couple of degrees. Likewise it is a perfect insulator, being incapable of conducting electricity regardless of the amount. This perfect insulator status also confers one last property. Adamantine is perfectly non-magnetic, being unaffected by magnetic fields no matter the strength.

## Known Adamantine Objects

Due to the difficulty of production and the immense cost, each known item made of Adamantine has been hand-made by the Master of Metal herself. Acquiring it as a raw material is virtually impossible, and only the richest of people on the planet are willing to pay for a finished product. Below are the known objects made with Adamantine in their construction.

* Saisho: Forged by Kogane as a token of respect for the Yonko Daddy L. Legs, this sword is a monstrous affair measuring it at nearly one hundred and forty feet long. Kogane estimates its value is at 1,000,000,000,000 in just materials alone and took her nearly three months to make. It was also blackened by Kogane's Haki during the forging process, and as such is counted as among the Black Blades.

* Adamance: Kogane's personal set of forged armour, this set of full plate is likewise a monstrously expensive affair, its owner has spared no effort in making sure that in combat she is virtually indestructible. It is valued at nearly 150,000,000,000 by its owner.

* Prydwen: A set of boots that were commissioned by Phim D. Sera for her victory over Pandamonium Gauntlet, these boots provide the ultimate protection to their owner. They are valued at nearly 3,000,000,000.

* Epizò: Epizò is an Adamantine Xiphos blade, originally held in the hands of a now extinct nation. It was once known as the Treasure of Crete (クレタの宝 Kureta no Takara?).

* Justice: A shield constructed of adamantine requested by Ferrothorn Solomon. It was then given to Jupiter and has become his primary weapon in his main hand.

## Roleplay Usage

* While anyone can theoretically buy an item made of Adamantine, the price for such an item is astronomical, among the most expensive items in existence. As such, if someone wishes to purchase an item made of Adamantine in character, they most prove that their character would be able to afford such an item.
* For the context of most rps, just assume the Adamantine items are unbreakable. They generally do not have any noteworthy properties barring specific matchups, ie someone trying to shock someone through their sword.

## Trivia

* This idea was made by the author who wanted to make a super metal.
* This material was originally branded as Toughyrite until Kogane's Marketing agent raised objections to the name.
