This vintage 12-foot wooden folding ruler is a beautifully preserved relic from the world of precision craftsmanship — most likely used in hydrology, civil engineering, or water level surveying.
Designed for accuracy and portability, this fold-out stick features 12 inches-per-foot markings and metal joints that allow it to collapse neatly into a compact, pocketable form. Tools like this were essential for surveyors working in the field — especially when dealing with irrigation, land grading, or drainage measurements.
With its tactile aged patina and functional charm, it’s ideal for collectors of scientific instruments, or as a decorative piece for a workshop or office.
