A useful home toolkit is smaller than most starter bundles and stronger on repeat-use tools like a drill, tape measure, screwdrivers, pliers, level, and basic safety gear.
The most useful screwdriver knowledge is matching the driver shape to the screw head correctly so the tool seats fully and does not strip the fastener under pressure.
A claw hammer and a rubber mallet solve different household problems, because one is for driving and pulling metal fasteners while the other is for controlled force without surface damage.
An adjustable wrench and pliers overlap only a little, because one is meant for turning flats more cleanly while the other is better for gripping, holding, bending, and awkward shapes.
