Our Story
The Original
Sharp Edge Tester
In 1973 Underwriters Laboratories began work a team of engineers to develop a product that would test the sharp edges of manufactured products for safety in handling. The team recognized that everything from appliances and electronics to ceramic and metal fabricated parts has the potential to be dangerous if rough edges are not tested for sharpness. The goal of the collaboration was to create a device that could simulate physical contact with sufficient pressure to determine if the item represented risk for injury during normal handling.
This effort helped create the UL 1439 standard ‘Tests for Sharpness of Edges on Equipment’ and was the beginning of the Sharp Edge Tester solution. Over the years the product has been enhanced and improved, but the focus on helping to make safer products has not changed.
For nearly 50 years, we have manufactured and sold the highest quality handheld tester to customers around the world. Made in America from the highest quality components, our customers trust the durability and reliability of our products.
Our latest products, the Sharp Edge Tester SET-50™ and Tape Cap Kit TC-3™, have been specifically engineered to achieve the most current UL 1439 standard.
