How to distinguish between ordinary screwdriver and precision screwdriver?

Each of us will use some small tools, such as the common screwdriver, which is not often used, but it will be uncomfortable if we do not have it at hand, so we should choose a good screwdriver.
According to the classification of purposes, screwdrivers can be divided into ordinary screwdrivers and precision screwdrivers. Ordinary screwdrivers are commonly used in families, including slotted, cross, flower and other different screwdriver heads. For example, this Stanley chrome vanadium steel powerful flat screwdriver is made of chrome vanadium steel, which has high hardness, good toughness and wear resistance; The surface of the screwdriver shank is chrome plated, which is both rust proof and beautiful; The cutter head is blackened, magnetic, and easy to operate; The handle of the screwdriver adopts a special octagonal section design to improve the torque; The rubber plastic double material handle is comfortable to hold and can prevent spinning and slipping. We should also choose such a screwdriver with excellent design and reasonable material when purchasing.
When selecting a screwdriver, we need to pay attention to the type of screwdriver head, handle design and material. Since there are many types of screwdriver specifications and screwdriver head shapes, we can prepare a complete set of screwdriver combinations for emergencies. For example, Stanley 10 piece screwdriver household combination set 62-511, which basically includes all the most commonly used types, even has a hook shaped screwdriver head that can be used for prying, which can be used as a nail lifter. In addition, the shared handle is designed with anti-skid particles, which makes it more stable and comfortable to hold. The triangular handle is used at the end to improve the torque and prevent slipping.
The precision screwdriver is mainly used for the delicate work of disassembling and assembling mobile phones, electronic components, repairing glasses, etc. It is mostly used by professionals. If you are a manual or repair enthusiast, you can also prepare a set for yourself according to your needs. Of course, we ordinary people can also prepare a set.
