二、美工刀的使用 1. 正确握持：使用美工刀时，应将刀柄握在手中，用大拇指和食指控制刀片的运动方向。注意保持手部稳定，避免晃动。 2. 切割技巧：切割时应保持刀片与被切割物垂直，避免斜切。对于较厚的物体，应一次只切割一小部分，避免用力过猛导致刀片折断或滑动。 3. 保护措施：在使用过程中，要时刻注意安全。避免将手指靠近刀片过近，以免发生意外。同时，要定期检查刀片是否松动或损坏，及时更换。 三、翻译成英文 **Essential Guide for Beginners: How to Choose and Use Art Knife Properly**

I. Selection of Art Knife 1. Material Selection: The blade material of art knives is crucial. It is usually divided into stainless steel and high-speed steel. Stainless steel blades are durable and rust-resistant, suitable for long-term use; high-speed steel blades are sharper and suitable for fine work. 2. Handle Design: The handle design should be ergonomic, comfortable to hold, and non-slip. For beginners, choosing a handle that is moderately sized and easy to grip is more appropriate. 3. Brand Reputation: Choose an art knife from a reputable brand for better quality and after-sales service. II. Use of Art Knife 1. Proper Grip: When using the art knife, hold the handle in your hand and control the movement of the blade with your thumb and index finger. Keep your hand steady to avoid shaking. 2. Cutting Skills: Keep the blade perpendicular to the object being cut during cutting to avoid diagonal cuts. For thicker objects, only cut a small part at a time to avoid excessive force that may cause the blade to break or slide. 3. Safety Measures: Always be aware of safety during use. Avoid placing your fingers too close to the blade to prevent accidents. Regularly check if the blade is loose or damaged and replace it promptly.
