Differential heat treatment is a method used to alter the properties of various parts of a steel object differently, producing areas that are harder or softer than others. This creates greater toughness in the parts of the object where it is needed, such as the tang or spine of a sword, but produces greater hardness at the edge or other areas ...
Steel's exact flex and strength vary dramatically with heat treating. If steel cools quickly it becomes martensite, which is very hard but brittle. Slower and it becomes pearlite, which bends easily and does not hold an edge. To maximize both the cutting edge and the resilience of the sword spine, a technique of differential heat-treatment is used.
On the other hand, the exposed edge cools very rapidly, changing into a phase called martensite, which is nearly as hard and brittle as glass. The hamon outlines the transition between the region of harder martensitic steel at the blade's edge and the softer pearlitic steel at the center and back of the sword. This difference in hardness is the ...
Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact ...
Case knives are made with blades usually stamped from domestic chromium-vanadium steel alloy or stainless steel, and hardened using proprietary heat treatment methods. Knife handles or scales are made of a variety of materials, from the more common synthetic materials to natural materials like Brazilian cattle bone, India stag, buffalo horn ...
Heat treatment provides an efficient way to manipulate the properties of the metal by controlling the rate of diffusion and the rate of cooling within the microstructure. Heat treating is often used to alter the mechanical properties of a metallic alloy, manipulating properties such as the hardness, strength, toughness, ductility, and ...
In 2010, Kershaw won "American Made Knife of the Year" for the Tilt (model 4001) and Shun won "Kitchen Knife of the Year" for the Shun Premier line. [11] In the 2011 Blade Show, Zero Tolerance's 0777 won "Overall Knife of the Year," the ZT-Rick Hinderer 0560/0561 won "Collaboration of the Year," and the Shun Fuji line won "Kitchen Knife of the ...
