1. Blade Material The blade is the core part of a utility knife, and its material directly determines the blade's sharpness, durability, and cutting performance. Common blade materials include stainless steel, carbon steel, and high-carbon steel. High-carbon steel blades are widely used due to their high hardness, wear resistance, and excellent cutting performance. 2. Handle Material The handle is the operating part of the utility knife, and its material directly affects the comfort and feel of use. Common handle materials include plastic, metal, and wood. Plastic handles are lightweight and affordable, while metal handles are more durable and provide a better grip. Wooden handles give a warm feeling but require attention to moisture and cracking prevention. II. Performance of Utility Knives 1. Sharpness Sharpness is one of the most important performances of a utility knife. High-carbon steel blades have high hardness and sharpness, enabling easy cutting of various materials. Additionally, the grinding process of the blade also affects its sharpness, with fine grinding processes making the blade more acute. 2. Durability The durability of a utility knife mainly depends on the material and manufacturing process of the blade. High-carbon steel blades have high hardness and wear resistance, maintaining their sharpness for a longer period during use. Furthermore, reasonable manufacturing processes and heat treatment techniques can also improve the durability of the blade. 3. Operating Comfort The operating comfort of a utility knife depends mainly on the material and design of the handle. Quality handle materials and ergonomic designs can make operators feel comfortable during use, reducing hand fatigue. Additionally, the installation and dismantling of the blade should be simple and convenient for operators to replace and maintain. III. Conclusion In summary, the material and performance of utility knives have a crucial impact on their
