What is another word for misused?

Phillip misappropriated the use of the screwdriver when he should have used a crowbar. His misuse of the screwdriver caused him to have the screwdriver jerk back and poke his eye. Now that he knows it is wrong to incorrectly use tools not meant for other tasks he will not maltreat his tools anymore. His eye still hurts reminding him not to abuse his tools.
