If something is scrimshawed, it has designs or pictures carved into it, usually on bone or ivory.
Scrimshawed things are often thought of as old-fashioned or traditional, and the word can make people think of sailors or the sea.
Examples:
The scrimshawed whale tooth had a picture of a ship on it.
He scrimshawed a beautiful design on the bone.
The scrimshawed necklace was very old.
I scrimshawed my name on the rock.
The scrimshawed treasure chest was full of gold.
She scrimshawed a story on the old bone.
