Midori Aluminum Multi Ruler black

The Midori folding ruler in matt black anodised aluminium measures 30 cm when unfolded and folds down to two 15 cm segments – compact enough for any pencil case or notebook pouch. The scale is laser-engraved: sharp, permanent, and resistant to wear. For those who work with precision, here's a tool that handles both measuring and cutting equally well.

Features

• Laser-engraved scale: Millimetre-accurate divisions that won't rub off or fade – even after repeated craft knife use, measurement accuracy remains intact.
• Suitable for cutting: The aluminium edge is stable enough to serve as a guide rail for craft knives and scalpels; no plastic edge that slips or gets scored.
• Folding mechanism 2 × 15 cm: Folded to 15.5 cm, the ruler fits standard pencil cases and pocket formats – unfolded, you get the full 30 cm.
• Angle function: In the half-open position, the hinge acts as an adjustable angle – useful for layouts, angled cuts and parallel lines.
• Matt black anodised aluminium: Cool, smooth feel, lightweight, no glare when reading – and the black surface makes the engraved scale particularly high-contrast.
• Scale starts at the ruler edge: The zero line sits directly at the ruler's edge, not set back – this allows precise measurement even in corners and at margins.

Use & Tips

• Bookbinding & paper workshop: As a cutting ruler for bone folders and craft knives – the aluminium edge provides secure hold without giving way under pressure.
• Journal & bullet journal setup: Page layouts, table grids and margin lines can be drawn across an A4 or A5 spread in one go with the 30 cm format.
• On the go and travelling: When folded, the ruler disappears into your pencil case next to your notebook – no creasing, no overhang.
• Origami & paper crafting: Draw precise pre-fold marks on paper without damaging the surface – the aluminium edge glides smoothly.
• Angle measuring: Position the hinge at a specific angle, use a set square to read and fix the angle – handy for repeated angled cuts.

For Paper Enthusiasts

Aluminium rulers are anodised to seal the surface against scratches and oxidation – with the black finish, a coloured oxide layer is created and worked directly into the material, not lacquered on top. The laser engraving then cuts the scale into this layer: the result is a division that sits flush with the surface and is barely noticeable to the touch, but optically razor-sharp. For anyone working with craft knives or scalpels, this makes a tangible difference to printed or glued-on scales that can lift under the blade.
