"Pointed" or "sharp" refers to an object that has a fine edge or a tapering end, making it capable of piercing or cutting through materials. Common examples include knives, needles, and certain types of tools. The sharpness of an object can be measured by how easily it can penetrate a surface, which is often influenced by the angle and material of the edge. In nature, many animals possess pointed features for survival. For instance, the teeth of a shark or the claws of a hawk are designed to catch and hold prey. Pointed structures can also be found in plants, such as the thorns of a rose, which serve as a defense mechanism against herbivores.
