‘The unworked steel arrives in my workshop and I have to make swords out of it. Do you know how that is done? First, I heat the metal until it is red-hot, then I beat it mercilessly with my heaviest hammer until the metal takes on the form I need. Then I plunge it into a bucket of cold water and the whole workshop is filled with the roar of steam, while the metal sizzles and crackles in response to the sudden change in temperature. I have to keep repeating that process until the sword is perfect: once is not enough.’
The blacksmith paused for a long time, then went on:
‘Sometimes the steel I get simply can’t withstand such treatment. The heat, the hammer blows, the cold water cause it to crack. And I know that I will never be able to make it into a good sword blade. Then I throw it on the pile of scrap metal that you saw at the entrance to the workshop.’
