Midwest Tools Upright Left Snip is a professional tool designed to cut holes in metal ductwork. It features a 90-degree head for use in tight spots and overhead, and can be used in a push or pull motion. The forged blades provide the longest cutting life, and can cut straight and tight curves in sheet metal up to 24 gauge cold rolled steel. The center pivot bolt is threaded into the bottom blade to keep the tool in alignment longer.
