Two Types of Screwdrivers
A screwdriver is a hand tool that is used in conjunction with devices called screws. A screw is a cylindrical device with a slat or rounded head on one side, each with a distinguishable indentation (in which specific screwdrivers are inserted to drive the screw) and are pointed and ridged on the other end. These ridges allow for the screws to have an easier time being driven into the chosen material.
By matching the correct type of screwdriver to the complementary screw a person can apply pressure with a rotational force as a way to drive the screws into the wood/sheetrock or other material. Harder substances may call for a drill or a mechanical screwdriver but primarily around the house every home owner should own the following two basic screwdrivers: the slotted screwdriver and the Phillips Head screwdriver.

The Slotted Screwdriver which is also known as the “flathead” or “turnscrew” driver and is characterized by its flat-bladed head. It looks similar to this shape of a minus sign or similar to this shape, – . You may have seen some people use a coin to unscrew specific screws, which is normally where a slotted screwdriver comes in handy. These are the most basic screwdrivers available and are useful for not only its obvious purpose, but for prying and opening paint can lid. The slotted screwdriver is available in numerous sizes.
The Phillips Head Screwdriver is the most popular screwdriver out there. If someone ever needs a Phillips Head screwdriver they are talking about the one with a tip that is shaped like a plus sign, or graphically the tip is shaped like this +. The cross shape is ideal in that it allows a little more control when driving a screw. Don’t have a Phillips Head screwdriver lying around? No problem, if you have a small slotted screwdriver on hand chances are it may be able to fit into one of the two slots in the phillips head screw which allows you to be able to drive or remove the screw without the aid of the Phillips Head screwdriver.
Screwdrivers have been around since the late 15th century and are still one of the most successful and efficient hand tools available. They are inexpensive and extremely useful items to own. Stock up on at least these two types of drivers and you should be set for any basic household projects.
