Tin Snips

Aviation snips (or tin snips) are leverage-multiplying hand tools for cutting sheet metal, plastic, and vinyl, designed with compound action for easier cutting and less hand fatigue, coming in straight, left-cut (green), and right-cut (red) (clockwise/counter-clockwise) versions for different cut directions, ideal for HVAC, roofing, and metal fabrication. Key types include straight (for straight lines), left (for curves to the right), right (for curves to the left), and bulldog (heavy-duty notching/trimming) snips, featuring forged blades, serrated jaws for grip, and often ergonomic handles for precision and durability
