A tool container has a pair of housing members pivotally coupled with one another to provide an opened and closed position. At least one of the members defines a cavity to receive tools. The cavity is defined by a base and a wall extending from the base. A tool retaining insert is permanently secured in the cavity. The insert and wall include tenons and grooves to secure the insert in the housing member. Also, an arcuate locking mechanism is included to maintain the pair of housing members in a closed position.
