Blades can be made from various materials, including stainless steel, carbon steel, and ceramic, each offering different levels of durability and sharpness. They come in various shapes and sizes, tailored for specific tasks, such as kitchen knives for food preparation or utility knives for general use. The design of a blade typically includes a handle for grip and control, allowing users to apply force effectively. Blades are essential tools in many fields, including cooking, crafting, and outdoor activities. Proper maintenance, such as sharpening and cleaning, is crucial for ensuring their longevity and performance.
