The QSP Penguin Plus Linerlock Pocket Knife is a premium upgrade to the popular Penguin design, featuring high-end materials and a slightly larger profile for enhanced everyday carry performance. The knife features a 3.38-inch CPM-20CV stainless steel blade with a rugged black stonewash finish that offers exceptional edge retention, corrosion resistance, and a finish that helps conceal wear from daily use.
The blade provides smooth slicing performance and excellent cutting control, making it ideal for opening packages, light utility work, and everyday cutting tasks. A thumb stud allows for quick one-handed blade deployment, while the linerlock mechanism ensures secure and reliable blade lockup during use. The extended tang improves handling and provides added control when opening or closing the knife.
The black titanium handle offers lightweight strength and long-lasting durability, while the copper foil carbon fiber inlay adds a bold visual accent with layered carbon fiber texture and metallic copper highlights. Titanium construction provides excellent corrosion resistance and a comfortable feel in hand. Measuring 4.5 inches closed, the Penguin Plus offers a slightly larger grip while remaining easy to carry with the stainless pocket clip and integrated lanyard hole.
Whether you're looking for a premium everyday carry knife or an upgraded version of the classic Penguin design, the QSP Penguin Plus combines top-tier blade steel with durable titanium construction and striking carbon fiber details.
