A small, sharp knife such as a paring knife or a steak knife will often reach deeply enough into the crosshair pattern of the screw's head. However, if the screw is in too tight, you might permanently twist the blade without loosening the screw. So, a pair of vise grips can be used to slightly crush the head of the screw in order to gain a grip. Pliers often just do not give enough grip, and channel locks are often too large and unwieldy for the circumstance.
One way to remove a broken screw without using an extractor is to drill a small hole into the center of the screw and then use a screwdriver to turn it out.
The Philips screwdriver is named after its inventor, John P. Thompson, who patented the design in the 1930s. The design features a cross-shaped tip that helps prevent the screwdriver from slipping out of the screw and provides better torque for tightening or loosening screws.
One way to remove a broken screw from wood without using an extractor is to drill a small hole into the center of the screw and then use a screwdriver to turn and remove it.

Phillips head screwdrivers only work on Phillips head screws--which are ones with an "x" indentation on the head of the screw. A straight screwdriver works on screws with a single line indentation on the head of the screw.
There are 4 Philips screws that hold the steering column cover together.They are located underneath. Two in the front, two in the rear.Pop the cover off and you will have access to the ignition switch.On the left side, there is the electronic part of the switch that is held in with a Philips screw. To take this screw out, you will need an offset screwdriver, or one of the Philips screwdrivers with a very short handle.
To remove a stripped Phillips screw, you will need a screwdriver with a slightly larger size than the stripped screw head, or a screw extractor tool specifically designed for removing stripped screws.
The Phillips screwdriver was created by Henry F. Phillips (1890-1958) who was a U.S. businessman from Portland, Oregon . The Phillips-head ("crosshead") screw and screwdriver were both named after him .
You can unscrew a screw without a screwdriver by using alternative tools like a coin, a butter knife, or pliers to turn the screw in the opposite direction until it comes loose.
A Philips head screwdriver, unlike a flat head screwdriver is slightly tapered to the point and has a characteristic + point or nose.Screws with a "Phillips head" have an inverse + profile rather than a single groove of a normal screw.This means that when the screwdriver is inserted into the screw is catches at 4 points (along the +), rather than along a single line. If you add up the surface area of the groove of a Philips screw to a similar (similar size) single groove screw you will notice that is is much larger; this means that the screwdriver has more surface area on the screw head and that it is divided over 4 contact points. This allows the Philips screw to be tightened with more torque than a traditional screw before the head shears off.
