| Abstract Scope |
The tanto is a short blade that originated in Japan. Hirazukuri refers to the edge geometry, denoting that the blade is convex from spine to edge. It was originally worn by the samurai class as a weapon but then transformed into a more ornamental blade. The tanto was hardened using a differential heat treatment that involves applying clay along the spine of the blade. We will replicate this technique while also experimenting with cryogenic quenching. We hypothesize that the additional quenching will convert retained austenite to martensite, increasing strength and hardness. Scanning electron microscopy and optical microscopy will be used to characterize the microstructure of our blades. Mechanical testing will be performed to determine the mechanical properties of the blade.
