Blade is a strong and sharp-edged tool or weapon typically made of metal. It is used for cutting or thrusting purposes and is often found on knives, swords, and other bladed instruments. Blades come in various shapes and sizes, each designed for specific tasks such as slicing, chopping, or stabbing. They can be single-edged or double-edged, and some blades even have serrated edges for more precise cutting. Blades are commonly used in everyday tasks as well as in combat and survival situations.
