There are many domains today in which the term "tools" is referred to. Let's take for example website design. Web design needs colors, white space, text and so on and for the creation of these you need certain programs which are referred to as tools. They will help you gradually build up your work in a proper and easy way.
Another domain where we can find tools is the industry. There are practically thousands of them that were specifically designed to cope with various problems; either they require bigger or smaller such helpful objects. Thus we get to talk about the importance of them and the different situations they can be used.
Let's say that you broke your sink because you were too drunk last night and cracked it with your rock hard head or you just chipped it with your car keys when you angrily threw them away for unknown reasons. Removing your sink requires proper equipment and if you are not good at it you should better call in a plumber.
Thus we can safely say about them that they are identifiable by use. They are mostly used in enhancing already given abilities and for this example we can take a hammer and its striking ability which helps deliver efficient work. Certain body parts or functions can be successfully replaced by them.
Most people will always go for the easiest to handle. No one likes to drag around something with them which is hard to use and also is heavy (considering we are talking in industrial terms).
Also, the design is very important when we are dealing with a tool those we might use in the challenges our daily lives meet us with. It is very important to have a tool which classifies as proper for the job that needs it as to be done more efficiently and easily. A tool which doesn't have a good design and is not constructed to compliment the human hand and thus facilitate good efficiency will most likely not be a best buy and will be disregarded by a lot of people who will certainly not be interested in buying it.
All things considered, a tool is something that can be found in various lines of work, either physical or virtual that are essential in the productivity process.
