Why you need this tool Combine several everyday measuring and layout functions into one compact instrument to save time, reduce tool changes, and avoid carrying multiple single-purpose tools. Maintains measurement accuracy and dependable performance in regular workshop or design use, so you can rely on consistent results across projects. Designed for professionals and hobbyists who need a versatile, durable tool for precise marking, measuring, and simple assembly tasks. Key benefits and problem solving Faster workflows: switch between ruler, protractor, compass, and inner hex key functions without reaching for another tool. Fewer errors: integrated angle and linear measurements reduce transfer mistakes when laying out cuts or patterns. Space and cost efficient: one tool replaces several, freeing up workspace and simplifying your toolbox. Main features Multi-function: combines ruler, compass/divider functionality, angle measure (protractor), and inner hex key in a single instrument. Dual measurement systems: includes metric markings (mm and cm) and imperial markings (inches) so it works with international and regional standards. Robust manufacturing: made using stamping, polishing and heat treatment processes to improve durability and preserve measurement accuracy over time. Precision-focused: designed to hold form and function under regular professional use. Material and performance Metal construction refined by stamping, polishing and heat treatment for long-term wear resistance and dimensional stability. Retains measurement integrity through repeated use and handling, helping maintain reliable results on repeat jobs. Practical use scenarios Product design and model making: quickly mark straight edges, draw arcs or circles with the compass feature, and check or set angles for prototype parts. Woodworking and metalworking: measure and lay out cuts with metric or imperial scales, verify angles, and use the inner hex function for small fastener adjustments during assembly. On-site repairs and installations: use the ruler and protractor for quick measurements, then use the inner hex key to tighten or adjust components without swapping tools. How it stands out Integrates multiple measurement and minor assembly functions into one durable tool, reducing the need to carry separate instruments. Dual-scale markings eliminate conversion errors when switching between metric and imperial projects. Manufactured to maintain accuracy and usability through repeated professional use. Who it’s for Designers, craftsmen, technicians, and serious DIYers who need a reliable, multi-purpose measuring and layout tool that works across different measurement standards and tasks.
