Where did the scissor hands in "Edward Scissorhands" come from?

The protagonist of the film is a robot named Edward who has a human mind but a pair of scissor hands. His creator is an inventor who devoted almost his entire life to creating Edward. , however, the inventor died before he was finished, leaving Edward alone to live alone in the castle until Peg, a cosmetics salesman, appeared.

In fact, this movie is destined to be a story that starts with a fairy tale and ends sadly. Although I don’t like to use the word “destined” often, but you see, since Pegg took Edward out of the castle, From the moment you integrate into society, you are destined to end in tragedy. If Peg had not mistakenly entered the castle that day, Edward might have been living in the castle, ignorant of the world, and would not have to endure other sufferings in the world except loneliness. However, life is so unpredictable, and the appearance of one person will always change the other. A person's life.

His arrival was extremely lively, just like the beginning of every fairy tale. Everyone's eyes were so real and hot, like hospitality, and like they had discovered a new world. Edward used his scissor hands to trim the manor and cut various hairstyles for others. He never received payment, nor did he do it for any purpose. It was just pure love, or he finally found the value and meaning of his existence. .

When he was at a lively party, he stood next to the barbecue grill with a pair of scissors on his hands full of various vegetables and ingredients. There was a long waiting line in front of him, and his ears kept When compliments and ridicules came from people, Edward readily accepted them, because he felt that this would bring happiness to everyone, help everyone accept themselves faster, and face them with a smile even if they were ridiculed. His smile in the crowd was bright, just like the sky was blue and the sun was dazzling, he felt everything was beautiful.
