5 tricks of a regular screwdriver: many craftsmen don’t know, and sellers even less so
When choosing a set of screwdrivers in a hardware store, you need to focus not only on the price and manufacturer.
We'll tell you about five parameters that you should consider when buying screwdrivers.
How to choose a good screwdriver
Firstly, the screwdriver must be of a certain length. Although short screwdrivers are, of course, also needed in the household.
Secondly, the handle should fit exactly to the palm or slightly larger and consist of two components (hard and soft), without any growths, bumps, etc.
Thirdly, it is desirable that the rod have a hexagonal reinforcement.
This is a sign of a quality screwdriver designed for serious loads.
Fourthly, good quality is indicated by the rough processing of the metal on the splines.
Many manufacturers deliberately roughen the metal, and very expensive screwdrivers are coated with tungsten carbide.
Fifth, the screwdriver handle should have a wide opening. A special lever-amplifier can be inserted into such an opening.
