Why the Maun Aluminium Safety Straight Edge 500 mm (1710-050) works

Accurate work. Less rework.

0.042 mmover the full 500 mm

Over 500 mm, the bevelled working edge stays within 0.042 mm of true.
It gives you an accurate guide for mount board, decals, compact sign panels and smaller sheet materials.

Protect your fingers. Control the cut.

500 mmof recessed finger protection

The recessed profile keeps your steadying hand clear of the blade along the full 500 mm, and the foam-rubber backing helps stop slips on smooth materials.

Easy to position. Built to last.

40 × 10.5 mmsilver-anodised aluminium

Silver-anodised extruded aluminium keeps the 500 mm light and easy to set accurately on a standard cutting mat, and resistant to corrosion for years of use.

Best suited to

Manufacturing & Engineering

Choose the Maun Aluminium Safety Straight Edge 500 mm (1710-050) for marking, scoring and cutting smaller sheet materials and components on the bench.

Useful reach, light weight and non-slip backing make it easy to set accurately, and the recessed profile protects your steadying hand.

Model Making & Craft

Well suited to card, mount board, foam board and modelling sheet that have outgrown a 300 mm guide.

The 500 mm bevel gives you a clear, continuous line, without making the tool unwieldy on a standard cutting mat.

Sign Making

Use it to trim decals, printed film, self-adhesive vinyl and compact sign panels in one pass.

Foam-rubber backing limits movement on smooth media, and the bevel keeps the cut in view.

Interiors & Flooring

A practical choice for bench-prepared wallpaper, vinyl, laminate and veneer pieces up to 500 mm wide.

The safety recess keeps your fingers away from the blade during short installation and finishing cuts.

Glass Work

Suitable for scoring smaller panes and glass strips where close control is needed.

The grippy backing keeps it steady on the smooth surface, and the protected hand channel keeps your fingers out of the scoring tool’s way.

Leatherwork

Use it for wallets, cases, short straps and small leather panels that can be finished within a 500 mm cut.

The non-slip backing helps steady the hide, and the bevel gives you a clear knife line.

Frequently Asked Questions

What is a 500 mm safety straight edge used for?

A 500 mm safety straight edge suits bench cutting and craft work: card, mount board, foam board, modelling sheet, decals, compact sign panels, short wallpaper and vinyl cuts, smaller glass panes and small leather panels.

Will a 500 mm straight edge fit on an A2 cutting mat?

Yes. A2 cutting mats are typically around 600 × 450 mm, so the 500 mm works along the length of the mat without overhanging.

Should I choose the 500 mm or the 600 mm?

Choose the 500 mm if most of your work fits on a standard cutting mat and you value compact handling. Choose the 600 mm if you regularly cut wallpaper, sign faces or panels that run past 500 mm.

Size check: is 500 mm long enough?

It’s long enough for the long side of an A3 sheet (420 mm) in one pass.
It’s too short for the long side of an A2 sheet (594 mm). For that, choose the Maun Aluminium Safety Straight Edge 600 mm (1710-060).
