1. Material selection: High-quality utility knives are usually made of stainless steel, which is both durable and sharp. In addition, the thickness and hardness of the blade are also factors to consider when making a choice. 2. Blade design: The angle and length of the blade are important for different needs. For example, shorter blades are suitable for fine carving work, while longer blades can be used for large-scale cutting. 3. Handle design: A good handle design should be ergonomic, providing a comfortable grip and being slip and shock resistant. Beginners can choose lightweight and well-handled models to practice with. 4. Price consideration: Based on your economic situation and needs, there is no need to pursue overly expensive products. Generally, products with a good price-performance ratio can meet basic needs and save beginners' expenses. **Use of Utility Knife** It is crucial to master the correct usage and maintenance techniques when using a utility knife. Here are some precautions to keep in mind when using a utility knife: 1. Maintain hand stability: When using a utility knife, keep your hands steady and avoid shaking. You can use a table or other stable surface to help maintain stability. 2. Control force: Apply moderate force to avoid damaging the blade or injuring your hands. Beginners should start with a light touch and gradually learn the appropriate force. 3. Pay attention to cutting direction: Choose the appropriate cutting direction and angle based on different materials and needs. Try to keep the blade perpendicular to the cutting surface during the cutting process. 4. Replace blade timely: When the blade becomes dull or damaged, replace it with a new one promptly to avoid affecting work efficiency and quality of work. 5. Cleaning and maintenance: Clean the blade and handle after each use to avoid damage to the blade caused by dirt and debris. Regularly maintain the utility knife, such as applying lubricating oil, to extend its service life.
