Terminology. The noun scissors is treated as a plural noun, and therefore takes a plural verb (e.g., these scissors are). Alternatively, the tool is referred to by the singular phrase a pair of scissors. The word shears is used to describe similar instruments that are larger in size and for heavier cutting.

What is the difference between shears and scissors in sewing?

The difference between “scissors” and “shears” is length and design of the handles. Scissors are smaller than 10” with two identical handles while shears are 10” or longer with one rounded bow for the thumb and a longer more elliptical bow for two or more fingers.

What are shears?

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.
