Early utility knives were loved by artists and craftsmen for their simple design and sharp blade. These knives were usually made of metal, with a relatively thick blade that could easily cut various materials. At that time, the blade was often designed in a special loading method, making it easy for users to replace the blade when needed. At the same time, the handle part of the knife was often designed in a simple and comfortable way, making it easy to hold and not fatiguing after long-term use. These classic utility knives focused on practicality in design and were widely used in drawing, carving, model making, and other fields. People had realized the importance of the practicality and durability of tools for work efficiency. II. Modern Development: Innovation and Change With the development of technology and changing needs of people, utility knives continue to innovate and change. Modern utility knives have undergone upgrades in materials and expansions and optimizations in functionality. In terms of materials, modern utility knives adopt more advanced metal materials such as stainless steel, making the knives more durable and resistant to rust. At the same time, some high-end products also use lightweight materials such as carbon fiber to reduce overall weight, making it easier to carry and use for long periods. In terms of functionality, modern utility knives are no longer just simple cutting tools. They are equipped with many practical functions such as clips, wrenches, and rulers. This multi-functional design makes utility knives not only suitable for traditional drawing and carving work but also widely used in daily life and work. In addition, modern utility knives have a more convenient and safe blade replacement method. Some products adopt an automatic locking system to ensure that no accidental injuries occur during blade replacement. At the same time, some high-end products also come with smart sensing systems that can automatically detect the usage status of the blade and remind users to replace it in time. III. Conclusion From classic to modern, the development of utility knives has witnessed the pursuit of tool design and practicality by humans. Whether it is the early classic design or modern advanced technology, it reflects people's pursuit of efficiency and convenience. Nowadays, utility knives
