Horimono is a term used to refer to various engraving patterns and decorations on Japanese swords, including katana. These decorations are hand-engraved into the blade of the sword and often have a symbolic or aesthetic meaning. Horimono can be engraved on various parts of the blade, such as the side surfaces (omote), the back of the blade (ura), or the back with the body of the sword (mune). Horimono motifs are often inspired by Japanese mythology, history, nature or religion. For example, you can find different kinds of dragons, gods, flowers, birds or geometric patterns. Each pattern can have its own meaning and symbolism. In the past, horimono were often used as marks of property or to identify the sword, but today they are primarily an aesthetic element that emphasizes the uniqueness and artistic value of the sword. Horimono are usually carved by hand by master artists with years of experience in the art of engraving craft. Each horimono is unique and contributes to the overall aesthetic of the sword. Their presence on a sword can also affect its value and price. Horimono are one of the many aspects that make Japanese swords such fascinating and prized works of art.
