The Tajima Sumitsubo V8 is a compact Japanese chalk line designed for precision, visibility, and easy maintenance on job sites. Its angled cut head improves tip visibility and makes it easier to hold the line during marking, especially in narrow areas or hard-to-reach corners.

Thanks to its Full Open system, the body can be fully opened without tools to simplify cleaning and line replacement. The V8 model also incorporates anti-leak seals to limit ink drying and a safety system with a retractable tip for greater comfort and safety during use.
