This series is a part of a program of five different wire brushes, each with a different application use: small surfaces, wide surfaces, and surfaces which require one or both hands. This product was created with the purpose of increasing productivity and efficiency. With objectives such as saving time and effort as well as being safe to use, the Wire Brush series adopts a set of new features. This include: an ergonomic soft-grip handle for maximizing gripping effort and comfort, a finger guard to prevent injuries, and a conical front shape to brush in corner areas. Since these tools have been developed for a wide range of user, the design process has gone through all the stages of development, with an emphasis on ergonomics, experimentation and validation. During these stages, dozens of prototype generations have been tested with different categories of users following detailed testing protocols in various application environments and laboratory. Important to realize that the success of these tools among users inspired competing companies to develop similar products with shared features and benefits.
