We have lots of tools in our daily life and normally use them in the usual way for intended purposes. Sometimes, however, we also use them in a different way.
For example, we can use a computer mouse for holding a paper.
It may be not the original purpose of the mouse. But in this situation, it does not seem so abnormal.
The reason why it is not that much weird,
I think, we already know that the mouse's shape and weights are fit for holding paper pieces. This is not all. I have faced similar situation in daily life so much. After all, I began to wonder where current tool shapes came from and how people can use tools instinctually depending on their shapes.
To find the answer, I traced back to the primitive ages that human being had started to use raw materials or natural objects for the first time.
