For those who don’t know, there are 2 types of 4 sided screwdrivers. One is called a Reed and there other is called a Phillips. Difference is that the Reed style comes to a point and the Phillips has a flat end. Most people don’t know this ( even techs) and don’t use the correct one for the job.
Have you ever seen a Arthur Head screwdriver?
(very rare, possibly only 4 made from the A head of a typewriter key)
The A on the screwdriver fits into the A hole on the screw.
