Precision in a straight line: Maun’s steel straight edges
When precision matters, even the simplest tools can make a significant difference. Whether marking out materials, cutting wallpaper, fitting floor coverings or checking the accuracy of a finished surface, a straight edge needs to do more than simply look straight

Maun Industries’ Steel Straight Edges are precision engineered to provide an accurate, reliable reference for checking, marking, scoring and cutting, time after time.
Expertly manufact
ured in England, Maun’s Steel Straight Edges combine high-quality carbon steel construction with a precision-finished bevelled edge, delivering accuracy of 0.001 inch per foot, or less than 0.1 mm per metre. Designed for professionals and serious DIY users alike, they provide a dependable reference edge wherever straight lines or accurate surfaces are essential.
Precision in every line
A straight edge may be a simple tool, but accuracy is critical when the quality of the finished result depends on a perfectly straight line or a surface being true. Maun’s Steel Straight Edges are surface ground to provide a smooth, comfortable finish, while the bevelled working edge allows users to see the marking line clearly and accurately.
That precision also makes the straight edge useful as an inspection tool. Placed against a surface, the bevelled edge can be used to identify uneven areas, such as bows, dips or high spots. With a light source positioned behind the straight edge, any light visible between the edge and the surface can indicate a gap and, therefore, an area that is not flat.
This simple method can be particularly useful when checking the accuracy of machined, fabricated or finished surfaces. Depending on the application, the straight edge can be checked in different directions across the surface to identify variations that might otherwise be difficult to see.
The 3.25 mm-thick carbon steel construction provides a substantial, stable edge that stays firmly in place during marking and scoring. Its thickness also makes the straight edge suitable for use with a metal scriber, providing a robust guide for more demanding applications.
For added durability, every straight edge is case hardened to HRC 57. This helps ensure the precision edge can withstand repeated use while maintaining its performance over the long term.

One tool, countless applications
Designed for tasks involving checking, marking, working and cutting in straight lines, Maun’s Steel Straight Edges are suitable for a wide range of professional and domestic applications.
For engineers, machinists, fabricators and quality inspectors, a straight edge can provide a quick and practical way to check the flatness or straightness of a surface. It can be used during manufacture or fabrication, before components are assembled, or as part of a final inspection to identify unwanted gaps or surface irregularities.
The same principle has practical applications in automotive work, where a straight edge can be used to check components and mating surfaces for signs of distortion or warping. It can also be useful when assessing workbenches, frames, panels and other surfaces where accuracy matters.
For flooring professionals, the straight edges provide a reliable guide when cutting and laying vinyl flooring, while also allowing the installer to check the condition of a surface before work begins. In decorating, they can be used when measuring, cutting and hanging wallpaper, helping users achieve clean, accurate results.
The tools are equally suited to woodworking, textiles, leathercraft and other handicraft applications where accurate marking and cutting are essential. For woodworkers in particular, a straight edge can be useful for checking the straightness of timber and other work surfaces, as well as guiding a cut or marking a line.
Available in a wide selection of metric and Imperial lengths, users can choose a straight edge suited to the scale of the task, from compact options for smaller craft and workshop jobs through to longer tools for flooring, decorating and larger workpieces.
Built for professional performance
Unlike lightweight plastic rulers, a steel straight edge provides the rigidity and stability needed to stay securely positioned when marking or cutting. This makes it particularly useful when working with materials that do not naturally lie completely flat.
The rigidity and precision of the tool are equally important when it is being used as a reference for checking a surface. A straight edge is only as useful as the accuracy of its working edge, which is why precision manufacture and surface finishing are so important in professional applications.
A built-in 6 mm hanging hole provides a simple storage solution when the tool is not in use, while each straight edge is supplied with anti-rust paper to help protect the surface during storage.
The combination of precision manufacturing, durable carbon steel construction and practical design reflects Maun’s approach to specialist tools: take a familiar tool and engineer it to perform better.
Timothy Scholes, Managing Director at Maun Industries, said: “A straight edge is one of those tools that can easily be taken for granted, but when accuracy matters, the quality of the edge really does make a difference.
“Our Steel Straight Edges are designed to give users confidence that the line they mark or cut against is genuinely straight, but they can also be used as a simple and effective way of checking the accuracy of a surface. By combining precision grinding with hardened carbon steel construction, we’ve created a straightforward tool that delivers professional performance across a wide range of applications.”
With more than 80 years of manufacturing expertise, Maun Industries continues to design and manufacture specialist tools in England that combine practical functionality with precision engineering. Its Steel Straight Edges demonstrate that even the simplest workshop tools can benefit from careful design, quality materials and attention to detail.
For professionals and serious DIY users looking for a straight edge they can rely on, Maun’s precision steel range provides accuracy, durability and dependable performance – whether checking a surface, marking a line or guiding a cut.
