Treasure Tree Adam

Adam Wood (宝樹アダム) is the strongest and highest quality type of wood found in the world. Its immense rarity makes it considered as a great treasure. Occasionally, this wood is sold on the black market. Because of its value, it is sold at a very high price. Franky managed to purchase some for 200,000,000.

Both the ships the Oro Jackson and the Thousand Sunny were made from this type of wood. The wood is capable of withstanding cannonballs and gun fire quite easily showing little wear over time. However, even ships built of this wood need a shipwright to look after them, as it is not completely invincible.

Franky explained about this wood by saying that once, long, long ago, a city had been completely destroyed. Fire rained and giant waves crashed. However, one tree was intact and that was the Adam Wood tree.

Trivia

 * Adam Tree is most likely a reference to the bible story of Adam and Eve with the Tree of Knowledge. This can be reinforced by the discovery of the Sunlight Tree Eve in Fishman Island.
 * The Adam Tree may also be a reference to a real tree. A Giant Sequoia, named Adam, is over 200 years old and grows in the Sequoia National Forest in California. It is the 20th largest giant sequoia tree in the world.
