Then began the attempts.
The first method attempted was using stone to process stone.
He took a particularly hard stone with sharp edges to chisel another stone.
He hoped there would be a difference in hardness, so that if the stone in his hand was harder, the stone below might be chiselled into a recess.
However, in reality, it's possible to smash the stone into pieces, and a large stone can be divided into many smaller pieces.
Carving a large stone into a round shape was quite difficult.
Not just generally difficult.
He first tried to see if any stone could be processed into a disk shape.
He found a naturally flat stone.
Then he used a stone weighing over ten pounds to repeatedly strike its edges.
The outcomes were difficult to control.
Either the strikes achieved nothing, the stone below fractured severely, or the stone in his hand cracked.
