Grimewood is a type of wood found in Tradelands. It is obtained by chopping trees with a Golden Axe on any non-spawn islands. Grimewood is known for its rarity due to dropping from axes that must be made from one material ingame, as well as its vivid, swamp green coloration.

When used to create tools, weapons, ships, and cannons, Grimewood will change the color of the wood to a swamp green color, and will give a crafted item the "Grimey" prefix (This is not applicable to ships).
