Treasure Tree Adam

Adam Wood 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 that 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.
