TRC brass ruler 15 cm
The TRC brass ruler is a compact work tool with an engraved centimetre scale over its 15 cm measuring length. The gentle bend on the reverse side — a distinctive design feature — lifts the edge slightly off the paper, so ink doesn't run under the ruler when drawing lines. Solid brass feels cool and substantial, yet sits comfortably in the hand.
Features
- Bend on the reverse side: The gentle curve on the underside gives the ruler stability and keeps the edge at a distance from the paper — ink won't seep under the ruler, delivering clean lines even with a fountain pen or India ink.
- Solid brass: The material gives the ruler noticeable weight, keeping it steady on the paper when drawing lines — no need to hold it down.
- Living patina: Brass oxidises through contact with skin and light. After just a few days of regular use, each ruler develops its own unique colouration — from warm gold through bronze to deep copper brown. No two rulers look the same after a year.
- Engraved scale: The centimetre divisions are engraved, not printed — remaining permanently legible even as the brass darkens over the years.
- Compact format: 15 cm measuring length, overall length approximately 16 cm — fits into any pencil case, the inner pocket of a notebook cover, or a travel bag.
Use & Tips
- Calligraphy and lettering: Anyone drawing straight lines with a fountain pen, calligraphy nib or brush pen benefits immediately from the raised bend: the edge guides without smudging fresh ink.
- Sketching and drawing: The weight of the brass ensures the ruler stays put when drawing lines quickly — even on smooth paper.
- Shape the patina actively: To speed up oxidation, rub the ruler briefly with a lemon wedge or simply leave it unwashed in your hand. To preserve the bright brass colour, wipe the ruler with a dry cloth after use.
- As a straightedge in a notebook: Combined with an A5 or B6 notebook, the length suits most page widths — ideal for quickly dividing pages into columns or sections.
- Care: Brass requires no special maintenance. Fingerprints and signs of use are part of the material, not defects.
For Desk Enthusiasts
Brass is a material that responds to touch: the fatty acids from skin, air humidity and UV light set off a slow oxidation process that changes the surface layer by layer. The result is a patina — with brass, typically a transition from light gold-yellow through warm amber to rich dark brown. This very process makes the ruler a personal object: the areas touched most frequently darken first, whilst the edges retain their shine longer. If you wish, you can reset the patina at any time with commercially available brass polish and polish it bright again — the brass underneath remains unchanged.
