Why the Maun Aluminium Safety Straight Edge 300 mm (1710-030) works

Accurate work. Less rework.

0.025 mmover the full 300 mm

Over its 300 mm length, the bevelled working edge stays within 0.025 mm of true.
That’s precise guidance for model parts, labels, decals and small components, where every cut is on show.

Protect your fingers. Control the cut.

300 mmof recessed finger protection

On short cuts, your hand is never far from the blade.
The recessed profile keeps your fingers clear, and the foam-rubber backing stops the edge skating on card, film and glass.

Easy to position. Built to last.

40 × 10.5 mmsilver-anodised aluminium

Silver-anodised extruded aluminium makes the 300 mm light enough to place and lift with one hand, and resistant to corrosion in the workshop or studio.

Best suited to

Manufacturing & Engineering

Choose the Maun Aluminium Safety Straight Edge 300 mm (1710-030) for marking, scoring and trimming small sheet components on a crowded bench.

Its compact, lightweight profile is easy to position.
The recessed hand channel, non-slip backing and accurate bevelled edge give you better control on short cuts.

Model Making & Craft

Ideal for card, mount board, foam board, styrene and acrylic model parts that fit within a 300 mm guide.

The short length gives you close control, the bevel keeps your line visible, and the recessed profile protects your fingers if a knife or scoring tool slips.

Sign Making

Use it for labels, decals, lettering and compact vinyl graphics, where a longer edge would just get in the way.

Foam-rubber backing grips smooth film, and the bevel guides an exact finishing cut.

Interiors & Flooring

Best for short wallpaper, vinyl and decorative-sheet cuts prepared on the bench.

It’s easy to line up in tight spaces, and it gives your steadying hand a protected position.

Glass Work

Suitable for scoring small panes and glass components where compact handling matters.

The non-slip backing keeps it steady on glass, and the recessed profile keeps your fingers away from the scoring path.

Leatherwork

Choose this size for wallet parts, tabs, small panels and short fold lines.

The grippy backing helps hold the leather in place, while the visible bevel and protected hand position keep your knife work under control.

Frequently Asked Questions

What is a 300 mm safety straight edge used for?

A 300 mm safety straight edge is for short, controlled cuts on the bench: model parts, card, mount board, foam board, labels, decals, small vinyl graphics, small glass pieces and wallet parts. Its compact size is easy to position where space is tight.

How does the 300 mm protect my fingers on short cuts?

You hold it with your fingers in the recessed profile, below and away from the blade path. On short cuts your hand is close to the knife, so that protection counts: especially if a blade or scoring tool slips.

Should I choose the 300 mm aluminium or the 12″ steel straight edge?

Choose the 300 mm aluminium safety straight edge for knife and scoring work where finger protection and grip on smooth materials matter. Choose the 12″ for scribing metal and heavy leather cutting, where weight and edge durability count for more.

Size check: is 300 mm long enough?

It’s long enough for the long side of an A4 sheet (297 mm) in one pass.
It’s too short for the long side of an A3 sheet (420 mm). For that, choose the Maun Aluminium Safety Straight Edge 500 mm (1710-050).
