The Engineering of Blade Metallurgy

A cutting blade is not a sharpened piece of steel. It is a precision thermodynamic and mechanical system.

For decades, bladesmithing and knife engineering operated under the fog of workshop folklore. Makers quenched high-carbon alloys into mystery oils based on visual furnace color, while theoretical textbooks remained locked in abstract academic jargon, offering no actionable guidance for real-world workshop thermal processing.

The Engineering of Blade Metallurgy breaks through this divide. Engineered under Swiss typographical rigor and validated by modern scanning electron microscopy, continuous cooling transformation (CCT) curves, and linear elastic fracture mechanics, this monumental 320-page treatise delivers the definitive foundation for knifemakers, tool engineers, and mechanical designers who demand mathematical certainty.

From the crystallographic dissolution kinetics of cementite to the non-slip ramp trigonometry governing frame locks under drop-tower impact, this volume leaves zero room for speculation.

• Treatise I: Continuum Metallurgy & Phase Kinetics: Austenitizing equilibrium, Arrhenius carbon diffusion dynamics, Andrews martensite start equations, retained austenite destabilization, and carbide crystallography (M3C, M7C3, M23C6, MC).
