Null Knives designs small-batch folding knives in the USA. Founded by Sean in 2020, the brand grew from a kitchen-learned appreciation for quality blades into creating EDC folders built for function and aesthetics. Null Knives develops unique designs emphasizing ergonomics, material quality, and manufacturing precision. The company launched with the Raiden folder in January 2022, which sold out within minutes during pre-order. Null Knives focuses on high-end production pieces manufactured to exacting standards, with designs moving from initial sketches through CAD and 3D printed prototypes before final production.
CPM MagnaCut Blade Steel Construction
The Raiden R2 features CPM MagnaCut stainless steel hardened to 63-64 HRC, upgrading from the original Raiden's Böhler M390. MagnaCut offers superior edge retention, corrosion resistance, and toughness, making it suitable for demanding cutting tasks. The 3.3-inch drop point blade receives flat grinds with finishes including belt satin, stonewash, dark stonewash with satin flats, and hand-rubbed treatments. Blade thickness is 0.12 inches with jimping on the spine for thumb traction during cutting.
Titanium Framelock and Milled Handle Patterns
Raiden R2 models use titanium framelock construction with redesigned pivot hardware and faux pivot collars milled flush into the frame for refined aesthetics. Three milling pattern options differentiate handle textures and weight: Smooth (standard finish), Aero (weight-reduced milling), and Type S (milled lines pattern). Handle finishes include glass bead blasted titanium, black PVD coating, dark stonewashed staticwash, and specialized treatments. The frames run on bearing systems for smooth deployment via dual thumb studs. Titanium backspacers have lanyard holes, and milled pockets on handle interiors reduce weight while maintaining structural integrity.
Contoured Ergonomics and Deployment Action
The Raiden features 3D contoured handles designed for all-day comfort with a slim profile measuring 0.49 inches thick. Overall length is 7.72 inches open and 4.41 inches closed. Weight varies by configuration from about 3.3 to 3.8 ounces depending on milling pattern and materials. The knife deploys via dual thumb studs on bearing systems, engineered for smooth, responsive action. Tip-up pocket clips in matching finishes provide right-side carry. Handle contouring creates natural hand positioning for extended use without fatigue.
Raiden Model Variations and Materials
The Raiden R2 offers multiple configurations combining different handle patterns, finishes, and blade treatments. Material options include standard titanium, black PVD titanium, and special editions with damasteel blades and exotic accents like "blurple" (blue-purple) hardware. Hardware finishes coordinate with handle treatments using satin, stonewashed, or color-matched components. Null Knives also produces the Raikou model with CPM S90V steel and 8.6cm blades, named after the mythical thunder beast companion to Raiden in Japanese mythology.
