WithArmour – WA2403-BK – Cajo I – Fixed Blade Knife – WASTEEL Two Tone Drop Point – SCFG10 – Black Red

The WithArmour WA2403-BK Cajo I is a purpose-built tactical fixed blade designed for reliability, strength, and precision in demanding environments. Crafted as a full tang, heavy-duty knife, the Cajo I-BK balances rugged construction with refined engineering, making it suitable for tactical use, outdoor survival, and everyday utility tasks. Designed by Löfflmann Andreas, this model reflects a modern approach to performance knives, combining premium materials with practical ergonomics. At the core of the WA2403-BK is its advanced laminated blade construction. Featuring WASTEEL™ technology—pairing 420J2 outer layers with a VG-10 core—the blade delivers a combination of corrosion resistance, durability, and excellent edge retention. With a hardness rating of 57–59 HRC, it is engineered to maintain sharpness while remaining tough enough to withstand heavy-duty applications. The Soldier Grine™ (Saber + Scandi grind) enhances cutting efficiency, offering versatility across slicing, carving, and piercing tasks, while the black Ti-PVD finish provides added wear resistance and a sleek, low-profile appearance. The handle is constructed from Black SCFG10™ (Carbon Fiber G10 composite) with a striking red G10 accent, delivering both durability and visual appeal. CNC machining ensures a precise, ergonomic grip that promotes comfort and control during extended use. The full tang design further enhances strength and balance, making this knife a dependable tool in both controlled and rugged conditions. Paired with a carbon fiber-look Kydex sheath, the Cajo I-BK offers secure carry and quick deployment. The included Tek-Lock clipper allows for versatile mounting options, while the addition of a paracord lanyard and T-Punch sharpener enhances its overall functionality. Packaged in a premium matte black presentation box, this knife is equally suited for collectors and serious users alike.
