Cutting-edge technology refers to the most advanced and innovative technology available. It is often characterized by its ability to improve existing products or processes, or to create entirely new ones. Examples of cutting-edge technology include lasers and razor blades. Lasers are devices that emit a highly focused beam of light, which can be used for a variety of applications such as cutting, welding, and marking. Razor blades are sharpened metal blades used for shaving and other grooming tasks. Both lasers and razor blades are examples of cutting-edge technology that have revolutionized their respective industries.
