Scissors “are characterized by two small blades (less than 6 inches long), which are riveted togethe”
“The term shears is used to describe scissors that more than 6 inches long. Shears can therefore be thought of as large scissors, which are designed for specific applications.”
“One common design difference between a scissor and a shear is that, typically, a shear has a larger handle on either one side. This is so that the user can accommodate more fingers into it, and apply more force needed to cut harder materials.”
