Credit Card Knife Sharpener for EDC and Field Maintenance Keep a flexible, nonmetal abrasive sharpening card in your wallet or small kit for pocket knife touch ups and light tool maintenance. The card has the shape of a credit card, so you can carry a useful abrasive surface without a full sharpening bench. Rough, Medium, Fine, and Extrafine Grits Pick the grade you need or choose the Four pack of all grits. Rough works faster for more worn edges, while Medium, Fine, and Extrafine let you work toward a smoother finish. Use light pressure and keep the original edge angle. Flexible for Small Jobs and Tight Spots Use the Sharpening Card flat for ordinary edges. Gently curve it when the shape of a blade or other small tool calls for a more flexible sharpening surface. Avoid sharp folds and protect your fingers from the cutting edge. Carry a Small Blade Maintenance Kit Add this card to a pocket kit, tool roll, or compatible wallet pocket. It is a useful companion to Grim's cutting tools, including the Adze Card and Bushcraft Survival Card. The abrasive will eventually wear with use. → How to Sharpen a Blade → All Sharpening Tools → Explore Survival Cards → Learn About Survival Cards → Tins and Containers → Dog Tag Tools → Micro Tools → Back to the Shop
