The invention relates to a multi-functional screwdriver including a shaft forming a pair of coplanar bends rotatably mounted to a handle having therein a compartment for storing a plurality of bits. A latch bolt is slidingly mounted to the latch bolt housing for movement in a plane substantially parallel to the plane of the pane between a first position and a second position. The first and second channels are decoded and the subdivided blocks of the first and second channels are interleaved if the first and second channels are synchronously subdivided. An excessive level of instability is established by engine calibration. Thus, cosmetic raw materials required for producing cosmetics can be contained in a single container so as to enable the simple production of cosmetics. A method for producing a scented stuffed toy has a mold preparing step, a latex injecting step, a polyurethane filling step, a scented material adding step, a foaming step and a demolding step.
