Tijeras

**Tijeras**

Tijeras, commonly known as scissors, are hand-operated cutting tools consisting of two metal blades pivoted so that the sharp edges slide against each other when the handles are opened and closed. They are widely used in various fields, including crafting, construction, tailoring, and everyday tasks such as cutting paper or thread.

The basic design of scissors has remained largely unchanged since their invention, though modern versions often feature ergonomic handles, reinforced blades, and specialized tips for precision cutting. Common types include general-purpose scissors, craft scissors, kitchen scissors, and surgical scissors, each tailored for specific applications. Kitchen scissors, for example, are designed with a serrated edge for cutting through tough materials like meat or bread, while craft scissors often have pointed tips for detailed work.

Scissors are essential in many industries, including manufacturing, where they are used for precise cutting of materials like metal, fabric, and plastic. In households, they serve as a fundamental tool for tasks ranging from simple paper trimming to sewing and DIY projects. Over time, advancements in metallurgy and engineering have improved durability, sharpness, and functionality, making scissors more versatile and efficient.

Despite their simplicity, scissors have played a crucial role in human history, evolving from basic stone tools to the high-tech precision instruments they are today. Proper maintenance, such as regular sharpening and cleaning, helps ensure their longevity and effectiveness.
