In this Katana the smith has selected Kobuse lamination as the lamination technique and clay tempering as the differential heat treatment tempering process. \u003cbr\u003eThe blade is laminated using the ‘Kobuse’ lamination process. Kobuse lamination involves laminating 2 types of metal to offer a hard brittle crust that is razor sharp and can keep the edge, but leave the core of the blade more soft and durable and able to absorb impact and avoid shattering. \u003cbr\u003e\u003cbr\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1082\/8749\/2436\/files\/Kobuse2107.jpg?v=1792840532\" alt=\"\" width=\"265\" height=\"238\"\u003e\u003cbr\u003e\u003cbr\u003eThe purpose of the clay tempering process is to further improve the sharpness of the edge and durability of the overall blade. It involves smearing clay on the blade during heating and quenching to offer a uniform hardness to the blade and remove weak points which can occur when the heating or quenching is less even. It also allows the smith, by placing the clay thicker on certain parts of the blade, to make the edge harder (thus more able to keep the famous razor sharp samurai edge) and the rest of the blade less hard but more able to absorb impact. \u003cbr\u003e\u003cbr\u003e\u003cimg style=\"width: 250px; height: auto; display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1082\/8749\/2436\/files\/diagram-katana-clay_tempered.jpg?v=1792840529\"\u003e \u003cbr\u003e\u003cbr\u003eThe wooden handle is wrapped in genuine Stingray skin (Samekawa) before the traditional cotton handle wrapping (Tsukamaki).

The wooden box, black sleeve, cleaning kit and stand are included. The hamon on this sword is real.
