Answer:
1. 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.
2. These come in lots of shapes and sizes because some are more suited to cutting through certain materials than others. So, by knowing what size drill bit to use you'll be able to make the right hole in the right position.
3. This stand helps prevent the hot iron tip from coming in contact with flammable materials or causing accidental injury to your hand. Most soldering stations come with this built in and also include a sponge or brass sponge for cleaning the tip.
