This Large Duckbill Pliers is a professional hand tool custom-built for wind instrument luthiers and instrument repair shops. Specially designed for saxophone, clarinet and other woodwind instrument maintenance work. The wide flat duckbill jaw provides a large contact area, which distributes pressure evenly when clamping and shaping instrument parts. It avoids point pressure damage and prevents scratching the precious gold lacquer on saxophone keys. Made of high-quality carbon steel, the pliers body features great hardness and long service life. The ergonomic non-slip soft grip handles reduce hand fatigue during long-time repair work. Perfect for many common repair tasks: key bending adjustment, shaft pin installation, cork trimming, sheet metal shaping and component holding during instrument restoration. A must-have tool for instrument repair technicians and music studios.
