However, a pencil is not just a simple writing tool; it hides many amazing properties behind it. Let's explore the many wonders of pencils together. I. The Origin and Evolution of Pencils The origin of the pencil can be traced back a few centuries ago. The earliest pencils were made with wood as the base and lead as the core (although it doesn't contain lead). With technological advancements and changing needs, modern pencils have undergone significant improvements in materials and expanded uses. II. Diverse Manufacturing Process Although a pencil seems simple, its manufacturing process is quite complex, from selecting the wood to cutting, grinding, and assembly, each step requires precise craftsmanship and strict quality control. This reflects humanity's pursuit of craftsmanship and attention to detail. III. Multi-functional Applications 1. Writing and Drawing: Pencils are one of the most common writing and drawing tools, with erasable ink and adjustable color depth, making them ideal for creation and modification. 2. Drafting Tools: Designers and architects often use pencils for sketching and initial design. 3. Art Creation: Artists use pencils for sketching and speed drawing to express their artistic inspiration. 4. Scientific Experiments: Pencils can be used for experimental records or labeling samples in scientific experiments.

5. Emergency Tools: In emergency situations, pencils can also be used as simple tools for digging or scraping.
