Industry & Occupation
Classification
Summary
A craftsperson who uses wood or metal to manufacture scaled folding rulers (kanejaku).
Description
Folding rule makers are artisans who produce folding rules (folding rulers) using wood or metal as materials. The work processes range from material selection, cutting, and polishing; scale engraving or printing; metal hinge installation; painting and finishing; to precision inspection and calibration. Since the accuracy of the scales determines the tool's reliability, high attention to detail and precision processing skills are required. In addition to traditional manual work, recent years have seen cases introducing CNC machine processing and CAD design. They mainly work in factories or small workshops, handling made-to-order production or OEM manufacturing.
Future Outlook
Demand is limited due to the spread of digital measuring devices, but niche demand remains for traditional hand tools and the DIY market. Advancement incorporating CNC processing technology is required.
