## Summary description

KS Tools 300.0111 is a half-flexible steel ruler designed for precise linear measurement tasks. Constructed from durable steel with a semi-flexible profile, it suits workshop, mechanical and inspection uses where a balance of rigidity and slight bendability is needed. The tool offers clear graduations for accurate measuring and reliable everyday use in professional settings.

## Long description

KS Tools 300.0111 is a half-flexible steel measuring rule designed for accurate linear measurement in workshop, mechanical and inspection environments. The semi-flexible steel construction combines enough rigidity for straight-edge measurements with limited bendability to follow slightly curved surfaces. Clear, permanently marked graduations support precise reading and repeated everyday use in professional tasks.
Advantages
The half-flexible steel profile provides a balance between stiffness and flexibility, allowing measurements on both flat and gently curved surfaces. Durable steel construction resists wear and maintains straightness over time while clear etched or printed graduations ensure legible readings. The compact, slim design is convenient to store in toolboxes or carry in a workshop apron.
Suitable for
 Workshop measurement of parts and assemblies
 Mechanical inspection and quality control tasks
 Layout work and marking on metal, wood or plastic
 Measuring slightly curved surfaces where a fully rigid rule is impractical
When it may not be suitable
This half-flexible rule is not intended for precision metrology where certified calibration and sub-millimetre traceability are required. For measurements on strongly curved surfaces, a fully flexible tape measure will provide better conformity. Extremely rough handling or exposure to corrosive environments can accelerate wear and affect measurement legibility.
Key specifications
 Material: steel with semi-flexible profile
 Length: 500 mm (as indicated by the model variant offer)
 Graduation: clear linear markings for millimetre-scale reading
 Profile: slim, flat measuring rule suitable for toolboxes and pockets
How to use
Place the ruler along the edge or surface to be measured, ensuring full contact for accurate reading. When measuring curved parts, flex the rule gently to follow the contour without forcing it beyond its designed bend. Read the graduation at the reference edge or mark point and transfer measurements or use the ruler as a straight edge for marking. Store the rule flat or hung to prevent permanent deformation and wipe clean after use to maintain clear graduations.
What to consider before purchase
 Required measurement length and whether a 500 mm rule fits your tasks
 Need for half-flexibility vs. a fully rigid or fully flexible measuring tool
 Material durability and resistance to workshop wear
 Visibility of graduations under typical lighting conditions in your workspace
Usage recommendations
Use the KS Tools half-flexible steel ruler for routine workshop checks, layout marking and inspecting assemblies where a combination of straightness and slight flexibility is beneficial. Avoid forcing excessive bends and keep the rule clean and dry to prolong service life.
