Push-Cut Sharpness
Lock-Up Geometry
Detent Bias
Bevel Grind Symmetry
Technicians complete unsupported newsprint push-cuts across the entire cutting belly. Blades must shear cleanly along heel, curve, and tip without snagging or micro-tearing fiber.
Frame, liner, and crossbar interfaces undergo manual pressure staging. We confirm engagement depth between thirty and fifty percent without slippage, lock stick, or vertical play.
Each folding blade is inspected for detent ball seating and retention tension. Folders must stay closed under inverted shake while breaking smoothly upon thumb deployment.
Optical calipers measure behind-the-edge thickness across five equidistant points. Secondary bevels exceeding two degrees of side-to-side variance return immediately to the manufacturer.
Metallurgical Performance Standards
CPM-Magnacut Matrix
Engineered without primary chromium carbides, Magnacut achieves sixty-two HRC while preserving remarkable toughness. We audit every batch for uniform heat treatment and apex stability.
CPM-S35VN Reliability
Niobium carbides enhance fine edge retention and ease of stropping. Our testing benchmarks verify consistent fifty-nine to sixty-one HRC hardness ratings suitable for high-abrasion tasks.
Uddeholm Elmax Composition
A high-wear powder metallurgy stainless alloy suited for hard outdoor use. We verify micro-bevel resistance across heavy corrugated board cuts before approving inventory.
Nitro-V Razor Apex
Formulated with nitrogen and vanadium for ultra-fine grain structures. This steel takes acute fifteen-degree edges and excels in culinary and utility slicing profiles.
Calibrated Knives Ready to Ship
Skip factory variances and inconsistent grinds. Every folding, fixed, and kitchen knife in stock has passed physical inspection on our Austin test bench.
