Final answer:
Cutting tools must have a sharp edge for greater pressure and efficiency, and they benefit from high-quality materials and design features like corrugated surfaces to improve performance.
Step-by-step explanation:
The important properties of a cutting tool include a sharpened edge, material, and design that allow it to exert high pressure and cut through materials effectively. A sharp cutting edge has a smaller surface area compared to a dull one, which means that for the same amount of force applied, a sharper tool will exert a higher pressure. This enables the tool to penetrate materials with greater ease.
Furthermore, certain features of a cutting tool, like its geometry or the quality of its materials, may also enhance its cutting efficiency. For instance, the innovation seen in biological systems, such as the tooth of a marine mollusk which displays an interleaved polycrystalline calcite matrix, reveals that textures like corrugated surfaces can increase grinding efficiency.
In the context of manufacturing and tools, these properties would be highly regarded by toolmakers for their potential to optimize performance.
