"Dry blades" refer to the edges of tools or equipment that have not been lubricated or maintained properly, leading to increased friction and wear. This condition can occur in various contexts, such as in lawn mowers, kitchen knives, or industrial machinery. When blades are dry, they can become dull and less effective, requiring more effort to use. Maintaining blades by regularly applying lubricants or oils can prevent them from becoming dry. This practice not only extends the lifespan of the blades but also ensures optimal performance. Regular maintenance is essential for tools like saws and scissors to function efficiently and safely.
