You will be home and see my adjustable wrenches?

Good enough is Jørn Knudsen originally trained as a machinist, but he has virtually throughout his adult life worked as a deputy head of department of the industry. And therefore is the link to the skiftenøglerne not so obvious, as if Jørn Knudsen had been a mechanic and always at work had an adjustable wrench in your back pocket.

Anyway, he is bitten by a mad spanner, and he has in the past 25 years gathered at the small and large versions of the almost legendary and, under all circumstances, indispensable – tool.

I was infected by a good friend sometime in the 1980s. He total on adjustable wrenches and suggested to me that I could do the same. And it fell I, acknowledge Jørn Knudsen, while he pulls out a particularly memorable copy down from the wall.

In dead straight rows
the Wall is completely overplastret with adjustable wrenches, big and small, new and old.

– here is the first edition, which comes from Bahco. It was patented in 1888 and sent to the market four years later. And it is a special spanner, for there is probably no more than ten of them back, says Jørn Knudsen.

On the long, straight variety is skiftenøglerne – which is the term he prefers – is hung up in an elaborate order. And approximately every tenth adjustable wrench from Bahco.

– It is one of the major manufacturers, so it is quite natural that these are the ones I have the most of. But in reality, it was the first adjustable wrench was invented by the German Stub is already in the 1840's, but he never obtained a patent on its product, emphasizing the Jørn Knudsen.

Movable jaws
There is of course a very large selection of the so-called ordinary spanners, which can still be bought in modern editions in any stores. But the unique collection of Jørn Knudsen in Hørning also holds numerous special editions of the tool.

– here is a bit special, because both of the jaws can be moved. It does not, however, particularly good hold on the nut, so the idea went away from the again. And the people here have a reversible jaw so that it can be used for various purposes, says Jørn Knudsen.

Actually, there are quite a few of his keys, which are meant as multiværktøjer, where there is the hammer, pincers and spanner. But the bulk of the large collection is clean adjustable wrenches.

Keys without spark
– The models are made in berylliumbronze, which is non-sparking. The keys are used on drilling rigs and in connection with dangerous liquids, says Jørn Knudsen, before he hangs the gold-colored adjustable wrench back in the right place.

the Collection does not grow in longer in the same rhythm as in the past, since there has become few and far between effects, as Jørn Knudsen does not have in advance.

– I will shoot at, that I bought ten a year over the past few years, and I don't have any expectation that it's going to go the other way. But I'm looking of course for what might be on the market, says Jørn Knudsen.

He takes a once a year at a big trade fair in Bremen and trying otherwise to visit the biggest Danish stumpemarkeder.

in the fine company
And so we know the each other within that field, and if one gets hold of something, so there it is not long before others hear about it, and maybe also try us. But there is far between the good fund, underlines the collector.

Jørn Knudsen is also a member of the J. P. J. the Company, which is an association that shares knowledge and experience regarding adjustable wrenches in general, and the inventor himself in particular.

– They send out a couple of times a year a newsletter, so we can follow what is happening. I have not yet had the opportunity to visit Enköping in Sweden, where it all took off, but I hope in one day can be done, says Jørn Knudsen.

in return he has visited many other countries, and he has, for example, downloaded adjustable wrenches home from Tunisia, Hungary and England.
