Standard angular Iris scissors come in different lengths to fit various needs. You can find smaller, delicate ones around 3.5 inches (or 8.9 cm) for precise work, up to bigger standard sizes about 5 inches (or 12.5 cm). They also have options like stainless steel for everyday use, super-cut blades for sharper edges, and tungsten carbide for extra toughness that lasts longer.
