Her hand reached for the tent peg, her right hand for the laborer's hammer. She struck Sisera, she crushed his head, she shattered and pierced his temple. (NIV)
She put her [left] hand to the tent pin, and her right hand to the workmen's hammer. And with the wooden hammer she smote Sisera, she smote his head, yes, she struck and pierced his temple. (AMP)
She put her hand to the nail, and her right hand to the workmen's hammer; and with the hammer she smote Sisera, she smote off his head, when she had pierced and stricken through his temples. (KJV)
