The Tajima SeF Sumitsubo EVO M is a compact Japanese chalk line designed for quick access and excellent mobility on construction sites. Thanks to its SeF Hook system, it can be attached directly to a belt via a compatible holder, eliminating the need for a tool pouch and significantly improving working comfort.

Equipped with a 20-meter line with automatic 10-meter rewind, this EVO M model incorporates several practical improvements, including an angled tip housing for better visibility and easier holding during marking. Its rubber seal system limits ink leaks and slows down liquid drying for long-term use. The body opens completely without tools to facilitate maintenance and line replacement.
