Everyone needs to have at least one flathead and Phillips-head screwdriver in their toolbox. In fact, I have about 30 of each. Beyond the obvious, screwing and unscrewing things, screwdrivers have a multitude of “hidden” uses.
In the above video, YouTuber CrazyRussianHacker shows off some clever ways to use the tool. For example, if you have a highly viscous liquid, such as oil, that you need to pour from one bottle to another but don’t have a funnel, just pour the oil along the shaft of a screwdriver into the container.
