Experience advanced mechanics and ergonomics with a new generation of cutting tools that deliver more strength， comfort and control. PowerArc Easy Action Aluminum Tin Snips boast intelligently curved blades that alter the angle between blades to give over 40% more power， especially during the toughest part of the cut. A radically ergonomic， spring-assisted handle prevents overextension， helps reduce hand fatigue， and features an open top loop， allowing you to rotate your hand over the handle to apply more power. In addition， Softgrip enhances dexterity and comfort， and a bigger bottom loop fits large gloved hands. Aluminum construction lightens the load， while replaceable stainless steel Micro-Tip blades ensure every cut is clean and precise.
