It's a long story, but it goes something like this ...
'Exact' was a company, founded around 1960 in Denmark, that manufactured propane torches. Although they were marketed as an industrial product (primarily in the roofing industry), they were quickly recognized as being very useful in the hot glass studio.
About 10-15 years ago, Exact was purchased by a German conglomerate called 'Rothenberger', and Rothenberger changed the name of the Danish facility to 'Rothenberger-Exact A/S'. After a couple of years, Rothenberger decided to shut down the facility in Denmark, and move the torch manufacturing to another one of their factories in Spain.
With the Danish factory being shutting down, the Danish management bought back the remains of the factory, and the rights to the name 'Exact'. They re-opened under the new name 'Exact-Denmark', and continued to sell the torches (that were now being made in Spain). Unfortunately, they were only able to stay in business for a year or so before having to close for good. Hence, the Exact name is no longer.
Meanwhile, production of the torches still continues in Spain. These are the same torches that were originally manufactured in Denmark, and are being made on the very same equipment. Rothenberger currently markets these torches under two brand names: the 'Super-Ego' brand name, and Rothenberger name. ARTCO carries the torches with the Rothenberger name on them.
So, ARTCO still carries the same exact torch (pun intended!); it just doesn't have the Exact name on it.
