Why are there so many different screwdrivers?
The reason for the different styles is cost and torque. Phillips screws are self-centering, making powered screwdrivers possible. They’re somewhat more expensive to produce than slotted-head. They tend to ‘cam-out’ easily under torque, making it hard to apply much torque.

Why are there so many different types of screw heads?
Answer: The primary reason for the wide variety of screw head drive types is to ensure the fact that you will never have the proper screwdriver close at hand when you need it.

What are the dangers of screwdriving with a screwdriver?
Phillips head screwdrivers are designed to “cam out”, which means they are designed to slip out of the screw, so you don’t over-tighten them. This also leads to their greatest pitfall. The greatest danger of screwdriving (new word, you read it first here) is stripping the screw head.
