1. The document describes the design process for scissors using an original evaluation system over 20 months from 2001. 2. Key steps included identifying problems with existing products, creating a design module, verifying the design approach, producing prototypes, testing with users, conducting user research trials, and narrowing designs to select the final design. 3. User testing and the original evaluation system were used throughout the design process to evaluate prototypes, materials, and other design elements.
