The Shinwa blade making process begins with each blade being hand forged at temperatures of up to 1,100 °F. These rough blades are then repeatedly heated, folded, hammered and shaped before being oil quenched and then straightened. Damascus steel blades are folded as many as ten times to yield up to 2,056 layers of beautiful Damascus steel. After quenching, the blade is then hand sharpened and polished by the swordsmith on a series of wet stones. Each set of these wet stones contains a finer level of silicate particles, which produces an even sharper edge than the stone before, until a razor-sharp edge is present. In the final stages of this painstaking sword-making process, the tsuka is wrapped and tsuba and other fittings are added before a thin coat of oil is added to the blade to prevent corrosion. Each Shinwa sword is then carefully packaged before being sent to premium sword collectors across the globe.
