The Fiskars PowerArc Easy Action Aluminum Tin Snips are ideal for cutting a range of heavy-duty materials, including aluminum siding, vinyl siding, light-gauge sheet metal, tin, soffit, fascia, drip edge, gutters and more. PowerArc™ design boasts intelligently curved blades that alter the angle between blades to give you 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. Plus, 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.
