The present invention discloses a method for manufacturing a manual tool, comprising: performing dual-frequency induction quenching on a first surface of a moment output part or a moment transmission part of the manual tool such that a quench-hardened layer is formed within a first depth range from the first surface of the moment output part to the interior of the moment output part or within a first depth range from the first surface of the moment transmission part to the interior of the moment transmission part, the hardness of the quench-hardened layer being higher than that of the body of the moment output part or the moment transmission part; the dual-frequency induction quenching being configured to simultaneously feed or introduce a high-frequency current and an intermediate-frequency current to the same induction coil to simultaneously heat the first surface of the moment output part or the first surface of the moment transmission part by the high-frequency current and the intermediate-frequency current, and then the moment output part or the moment transmission part being cooled and quenched. The present invention also discloses a manual tool manufactured by the above method. The manual tool subjected to double-frequency induction quenching according to the present invention has good abrasion resistance.

A ratchet driven screwdriver with bits storage has a body. A ratchet driving device has a ratchet, a lever, a ratchet housing, a ratchet spring, two L-shaped ratchets, a steel ball and a compression spring. A bits storage has a spring seat, two torsion springs, a storage tube, an axis column, and a bits box. When replacing the bits, the back cover is pulled to drive the storage tube. Currently, a pressure of the two torsion springs can extend to a tapered end of the axis column to release a vertical force, and the back cover is pulled apart. The two torsion springs extend to the other end of the axis column, and the vertical force can make the bits box pushed to the open state and locked, so that an alternate screwdriver bit can be selected with turning the back cover.
