When this craft appeared in commercials, this idea seemed very doubtful, but for some reason it turned out to be popular and they began to repeat it. There is nothing surprising in the use of a conventional incandescent lamp, even the manufacture of screwdrivers based on it, only the materials used are puzzling.
For crafts, you need an ordinary light bulb, with which part of the base is cut off and all the contents are removed. The inner part of the resulting container is filled with a cement mortar, it is this material that the DIYers liked to taste. However, the adapter for the screwdriver is placed in an iron base and fixed there with epoxy resin or cold welding.
There is no doubt, the design turned out to be quite convenient for a person’s hand, but you can only guess how much it will last under loads.
