Keep your DDR3 folding knife performing at its best or create a completely custom build with the DDR3 Replacement Blade Series. Designed specifically for the original DDR3 folding knife kit, these replacement blades provide knife makers with multiple options, whether you're replacing a worn blade, upgrading your build, or creating a blade entirely from your own design.
Crafted from premium AUS8 stainless steel, each blade is engineered for excellent toughness, corrosion resistance, and dependable edge retention. Tactical blade models are heat-treated and cryogenically treated, then finished with a smooth 600-grit satin surface for a clean, professional appearance and ready-to-install convenience. Builders seeking complete creative freedom can choose the unground blade blank, allowing them to create their own bevels, edge geometry, and final finish from raw stock.
Available configurations include tactical blades with or without a thumb stud, as well as a grind-your-own blade blank for experienced makers who want complete control over the finished design. Every blade is manufactured to fit the original DDR3 knife kit, making installation straightforward while preserving the knife's original fit and function.
Whether you're restoring an everyday carry, experimenting with a custom grind, or replacing a damaged blade, the DDR3 Replacement Blade Series provides the quality foundation your next project deserves.
