Iaito are practice swords used in Iaido, a Japanese martial art focused on the smooth, controlled movements of drawing and cutting with a sword. Unlike real swords, iaito are typically made of lightweight materials, such as aluminum or zinc, and have a dull blade to ensure safety during practice. They are designed to help practitioners develop their techniques without the risk of injury. Iaito come in various lengths and styles to accommodate different practitioners and their training needs. The use of iaito allows students to practice their forms, or kata, effectively while building muscle memory and improving their overall swordsmanship skills.
