Think of some of the small jobs you might do around the house that still require some sort of tool. For example, what do you need if you want to hang a picture or a shelf? Even flat-pack furniture requires some tools to assemble it. The types of tools you would need for these tasks are: a tape measure, a hammer, a screw driver set with flat head and Philips head screws and a level to make sure everything is straight.
Another task that frequently needs doing in some homes is unblocking toilets and sinks. While you might need to call someone to fix a big problem, very often it can be resolved using a plunger.
Here are a few other useful things to have in your tool kit:
Safety equipment such as: Breathing mask, gloves and safety glasses
As you can see, even if you do not like DIY projects, having a small tool kit at home can be extremely useful and help you do even the smallest jobs effectively.
