The design of scissors varied as the ages passed. The first tools looked like a couple of knives attached together with a springy band of metal. Over time, they evolved into a pair of metal edges joined with a pivot rod. Sharp ends are placed facing one another, and when operated - two blades slide along and against each other. The actual separating action depends on two major factors - shearing (which is a major force in low-quality tools) and cutting (common in high-quality instruments). These devices can vary in type based on their application - from school scissors to hair trimmers and branch cutters. Find the best solution at Mega Depot!
