Shaping metal with a hammer is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge . Smithing can also involve the other aspects of metalworking , such as refining metals from their ores (traditionally done by smelting ), casting it into shapes ( founding ), and filing to ...
A variety of blade materials can be used to make the blade of a knife or other simple edged hand tool or weapon, such as a sickle, hatchet, or sword.The most common blade materials are carbon steel, stainless steel, tool steel, and alloy steel.
The American Bladesmith Society, or ABS, is a non-profit organization composed of knifemakers whose primary function is to promote the techniques of forging steel blades.The ABS was founded by knifemaker William F. Moran, who came up with the concept in 1972 when he was Chairman of the Knifemakers' Guild; the following year, he introduced Damascus steel blades at an annual show.
Forging temperature is the temperature at which a metal becomes substantially more soft, but is lower than the melting temperature, such that it can be reshaped by forging. [1]
Bladesmith, Nuremberg, Germany, 1569 Bladesmithing is the art of making knives, swords, daggers and other blades using a forge, hammer, anvil, and other smithing tools. [1] [2] [3] Bladesmiths employ a variety of metalworking techniques similar to those used by blacksmiths, as well as woodworking for knife and sword handles, and often leatherworking for sheaths. [4]
Using the Smith chart, the normalised impedance may be obtained with appreciable accuracy by plotting the point representing the reflection coefficient treating the Smith chart as a polar diagram and then reading its value directly using the characteristic Smith chart scaling. This technique is a graphical alternative to substituting the values ...
Photomicrograph of martensite, a very hard microstructure formed when steel is quenched.Tempering reduces the hardness in the martensite by transforming it into various forms of tempered martensite.
Re-creation of part of a gun shop from the 1850s (photo circa 2015) A gunsmith is a person who repairs, modifies, designs, or builds guns.The occupation differs from an armorer, who usually replaces only worn parts in standard firearms.
