The Sharp Edge Tester is designed to evaluate toys for potential cutting hazards during normal use and after reasonable abuse, as specified under toy safety testing requirements. It determines whether accessible edges present a risk of injury to children. Built with a durable metal housing, the instrument ensures long service life and reliable performance.

The tester features a large footswitch for convenient operation and a special photoelectric sensor that indicates the applied force, ensuring the test force is accurately maintained at 1.35 pounds during testing. This eliminates reading errors caused by visual angle differences in conventional indicators. The unit operates on 220V AC / 50Hz power and includes built-in rechargeable batteries for flexible usage.
