This Hultafors folding rule is manufactured from downy birch with Swedish steel joints, enabling thin sections and great flexibility. The engineering scale reads in 1/10th and 1/100th of a foot alongside a traditional 1/16-in scale, the rule for people who calculate in decimals and build in fractions.

Specifications:

• Material: downy birch, heat-treated Swedish steel joints oiled at three points, water-based lacquer
• Scales: engineering 1/10 and 1/100 ft inside, 1/16 in outside, black and red markings
• Made in: Sweden by Hultafors (Swedish design since 1883)
