A hollow, cylindrical case comprises an upper seat, a cavity below the seat, and a lower channel. A locking device adopting an external locking mode comprises a plate secured onto the seat, the plate including a central hole, and a plurality of legs extended downwardly from the edge of the hole, each leg having an inwardly extended latched piece. Inserting a projection of a handle of a knife used in machining into the cavity and forcing through a channel surrounded by the latched pieces will move the latched pieces inwardly to lock a shoulder between the projection and the handle. An external locking mode can also be carried out in another embodiment. The invention can reliably secure the knifes in a storage.
