Crafted by master swordsmiths, the Shikoto Longquan Master Katana is made with techniques that date back to the Warring Period, over 2500 years ago. This hand polished Bronze Age sword is a magnificent addition to any collection. Each T10 high carbon steel blade has been hammer forged and clay tempered to produce a visible hamon line. Clay tempering imparts edge retention that’s simply without equal,prior to the intense heat of the hardening phase, Shikoto’s seasoned swordsmiths coat the newly formed, unrefined blade with clay – a thin layer along the edge, a thicker layer on the body and spine. When the blade emerges from the hardening forge, the clay layers’ contrasting thicknesses cause the steel to cool at slightly different rates, yielding two distinct hardness regions. Differential hardening gives these magnificent samurai swords a harder cutting edge and a softer spine, which is the hallmark of a high-quality weapon. The tsubas and handle fittings are made from solid iron. The wooden handles have traditional cord wrapping over genuine, tea-dyed rayskin. The solid brass collar provides an attractive contrast between the iron guard and the steel blade. A black lacquered and polished wooden scabbard with cord-wrapping houses the Shikoto blade. Also included with each sharpened Japanese sword is a certificate of authenticity with forging specifications, signed by the master swordsmith who crafted the blade. The Shikoto Longquan Master Katana is created with the same techniques as those used over 2,500 years ago to create a superior weapon for a remarkable warrior.
