Thread nippers are the perfect tool for cutting and snipping threads, heavier yarn and thick layers of fabric, and an innovative spring-action design gently opens the blades after each cut, reducing hand fatigue to make cutting virtually effortless. They feature precision-ground, knife-edge blades and a specialized handle designed to work with your index finger underneath the snip, thumb on top and middle finger through the loop to stabilize the nippers while your thumb and index finger push the blades together.Details:Silver colored4.5" x 1.69" x 0.53" (11.43cm x 4.3cm x 1.35cm)Spring-action open blades after each cutFor snipping threads, heavier yarn and thick fabricDouble-plated chrome-over-nickel blade
