The Sumitsubo Ichimonji Kikusui – Maru (round) model – is a traditional Japanese hand-crafted chalk line. Each piece is handmade, so the design and wood grain vary slightly, making each one unique.

Made from Keyaki wood (Japanese elm) , renowned for its robustness and natural elegance, this sumitsubo benefits from a Cashew finish that protects the wood while enhancing its appearance.

The Maru model features a more rounded and softer silhouette than the shoulder-mounted version, offering a harmonious aesthetic and a balanced grip. It comes with a handcrafted tracing tip (karuko) , essential for traditional ink tracing.

Both a precision tool and a functional work of art, this sumitsubo is aimed at demanding craftsmen as well as collectors of Japanese tools.
