The yokote of a katana is a straight line that separates the tip of the blade from the rest of the blade. It runs horizontally across the blade, perpendicular to the edge, and is one of the characteristics of the katana.
The yokote is created during the forging process, where the sword maker heats the blade and uses a hammer to give it the desired shape and curvature. The yokote is often accentuated during polishing, when the blade is carefully sharpened and polished to bring out the distinct line.
In addition to its aesthetic importance, the yokote also has functional importance. It helps strengthen the point of the blade, making it less likely to break or chip during use. The straight line also serves as a guide for the sword’s wearer, helping him or her to aim and strike the target accurately.
The yokote is an important aspect of the overall design of the katana, and variations in its shape and size can have a significant impact on the balance, maneuverability and cutting ability of the sword. A well-made yokote is the sign of a competent sword maker, and its presence is an important factor in determining the quality and value of a katana.
