Scissors are a common mechanical cutting implement characterized by two opposing blades joined by a pivot point. Functionally, they operate on the principle of leverage and shear stress, converting rotational force into a precise linear cutting action. When force is applied to the handles, the blades are forced to articulate, allowing the edges to meet and pass through materials. The efficacy of the tool depends on the material science of the blades, typically requiring sharpened edges to minimize friction and maximize the ability to separate materials. This mechanical design allows for controlled, repetitive cutting across various rigid and semi-rigid substrates.
