Among them, the pencil, as a convenient and practical writing tool, has experienced hundreds of years of development and evolution, becoming the style we are familiar with today. Today, let us explore the story of the writing tool that has traveled through time - the pencil. I. The Origin of Pencils The origin of the pencil can be traced back to ancient civilizations. During the European Renaissance, people began to use writing tools made of graphite and wooden sticks. The initial graphite pens did not require wooden wrapping, but for better grip and portability, craftsmen began to wrap graphite with wooden sticks, forming the prototype of modern pencils. II. The Popularity of Pencils With the advent of the Industrial Revolution, the production process of pencils has been greatly improved and upgraded. Mechanized production has greatly increased the efficiency of pencil production and made it relatively affordable, thus allowing pencils to spread worldwide. At the same time, the types and styles of pencils have also become increasingly diverse, from ordinary pencils to colored pencils, mechanical pencils, etc., meeting people's different writing needs. III. Technological Innovation of Pencils With the advancement of technology, the manufacturing process of pencils has also been constantly innovating. For example, the lead of modern pencils uses a special mixture of graphite and clay, which is fired at high temperatures to make it more durable. In addition, the appearance of pencils has also been improved many times, such as using environmentally friendly materials and adding anti-slip designs, making it more comfortable and safe for people to write.
