Pygmalion’s Carving Knife

Origin
Pygmalion was an ancient sculptor who carved a lifelike ivory statue of a woman, normally named Galatea. At the festival celebrating Aphrodite, goddess of love, he wished to meet a woman as beautiful as his sculpture. When he returned home, he kissed her to discover she had been granted life and animated, his wish fulfilled. In a newer and more satirical rewrite of the story, playwright George Bernard Shaw scripts a linguistics professor who bets he can make a simple girl pass for high class by instilling in her the vocabulary and stature of the wealthy.

Effects
Stabbing the knife into material will transfigure the material into whatever image the user is thinking of. If the knife is left in the item, it will become autonomous. If the knife is removed, the item returns to its inert state.
