Final answer:
The sharp edges of various tools are known as blades, which are designed for cutting or slicing operations in multiple contexts.
Explanation:
Many tools have sharp edges that are known as blades. A blade is typically the flat cutting part of a tool or weapon, sharpened on one edge and sometimes both, used for slicing or cutting. Various tools can have blades, including knives, saws, and machetes. For example, a pruning saw, integral in gardening, has a blade with teeth that can be measured in points per inch, indicating their cutting fineness.
A blade can also refer to the cutting part of hand tools, like those used for slicing through soil or cutting food, such as the incisors in our mouths. The term blade relates not only to the sharpness but also to the utility of the tool in different contexts.
