Knurls are small raised patterns or ridges that are intentionally formed on the surface texture of an object. They are typically found on cylindrical or rounded objects, such as the handles of tools or the edges of knobs, to provide a better grip for the user. Knurls are commonly made by cutting or rolling the surface material, resulting in a series of angular or diamond-shaped ridges.
The primary purpose of knurls is to enhance friction and prevent slipping when grasping an object. By adding these textured patterns, knurls provide a tactile surface that improves the grip and control, particularly in situations where hands may be slippery or wet. The raised ridges create additional points of contact with the user's hand, allowing for increased stability and handling precision.
Knurls are often seen in mechanical and engineering applications, as they play a crucial role in ensuring the effectiveness and safety of various tools and devices. Additionally, they can provide a decorative element, adding a visually appealing texture to an object's surface.

The distinct pattern and texture they create serve to improve functionality, ergonomics, and safety, making them a valuable feature in various industries and daily life applications.
