Abstract
A utensil is adapted to be held by a user and manipulated by the user's hand to operate on a workpiece. One feature of the utensil enables the user to gain mechanical advantage when locking and unlocking key-operated locking mechanisms by displacing a key from its stowed state to its extended state. Other features include a letter opener, a cap remover, and an abrasive element.
