Matsui Ruler

Super straight and deadly accurate

Hardened stainless steel metric rulers from the Matsui Precision Manufacturing company, for draughtsmen, engineers and carpenters everywhere.

Slightly sturdier than your average stainless steel ruler, with a natty yellow vinyl slip case and conversions tables engraved on the reverse (inches › mm, tap drill › mm, and W.W. UNF/thread › mm): needless to say, they won’t let you down.

Although still in use amongst artisan craftsmen and other traditionally-minded folk, Japan officially ditched the ancient shakkanho / 尺貫法 system of measurement in 1868, following the Meiji Restoration. That’s over 150 years of metric expertise at your fingertips.

Ever forward-thinking, Japan was one of the 17 original signatories to the 1875 Treaty of the Metre (a real thing, I assure you), so it’s no surprise Japanese rulers are some of the best in the world. It took the UK another 110 years to see the light and stop measuring things based on the length of the foot of a statue from 2,575 BC (again, not made up). Declare your allegiance to modernity with these metric wonders.
