20. SERRATED EDGE

A knife edge is typically serrated to enhance its cutting ability, especially on tougher or fibrous materials. Here are some key reasons why a serrated edge can be beneficial:

1. Increased Grip: The serrations create additional points of contact with the material being cut, allowing for better grip and reducing the chances of slipping.
2. Efficient Cutting: Serrated edges can slice through tougher surfaces, such as crusty bread or fibrous fruits and vegetables, without crushing them. The pointed teeth concentrate force, making cuts easier.
3. Longer Lasting Sharpness: Serrated knives tend to retain their sharpness longer than straight-edged knives because the points wear down more slowly. This means less frequent sharpening is needed.
4. Versatility: Serrated knives can handle a wider variety of tasks. They are useful in kitchens for cutting bread, tomatoes, and other items where a clean slice is required without pressing down too hard.
5. Reduced Friction: The unique design can reduce friction when cutting, allowing the knife to glide through materials more smoothly.

Serrated knives are especially favored in culinary settings for their practicality and effectiveness in diverse cutting tasks.
