The folding rule you recognize blindfolded

Hultafors - Ireland

The red end of the Hultafors folding rule has long been the sign of a true pro. Since its invention in 1883 our folding rule has changed how work trousers are sewn. And to this day it’s the craftsman’s first choice for measuring.

The Hultafors founder, Karl Hilmer Johansson Kollén, invented the folding rule in 1883. And ever since, we have manufactured folding rules for professionals all over the world. In fact, our folding rule is just about to complete its 12th turn around the globe. Since the start we have produced 480 million meters of folding rules.


An impressive number, yet also proof of how successful a smart idea can be. Especially if you devote 130 years to constant improvements. Because, even though today’s folding rule is very much the same as the classic invention of Karl Hilmer, many small changes have been made over the years.


Yet, the genuine feeling remains. The one that makes a professional craftsman recognize a Hultafors folding rule blindfolded. It feels so right lying in your hand, and the joints have that great smoothness when folding.

That is why we rarely need to explain for professionals why to choose the Hultafors folding rule. They already know. But how a folding rule is made, and how it came about – not everybody knows!

This is how we make them

In the folding rule factory, in Hultafors Sweden, we make our classic folding rule. The model 59, in downy birch with red painted ends. All parts are made locally by a skilled and efficient workforce.

First we build the machines

When you invent something there is nobody to follow, no parts to order. At Hultafors we have always taken pride in making everything ourselves.

We have always made our own machinery

Pick the right material

Apart from making our classic wooden folding rule we also offer folding rules made from aluminium and fiberglass.

Birch, aluminium or fiberglass?

Names tend to stick

In Swedish the folding rule is mostly referred to as a “tumstock”, meaning “inch rule”. This has been considered confusing since Swedes nowadays mostly rely on the metric scale.

Same name with inches and metric scale?
