A scissor is a handheld cutting tool that has been used for centuries across cultures and industries. It consists of two pivoted blades, usually made of stainless steel or another strong metal, that are sharpened along one edge. The blades are connected at a central point with a screw or rivet, allowing them to open and close in a shearing motion. Each blade is fitted with a handle, often shaped into loops, so the user can comfortably insert their fingers and apply force.
Structure and Design
Handles – Usually designed ergonomically, handles can be made of plastic, rubber, or metal. Some scissors are ambidextrous, while others are specifically designed for right-handed or left-handed users.
Blades – The cutting edges are typically slightly curved inward, allowing them to meet at a precise point for a clean cut. High-quality scissors are crafted to maintain sharpness and alignment over time.
Pivot (Screw or Rivet) – This joint is the fulcrum that gives the scissor its mechanical leverage. The tighter the screw, the more controlled the cut.
