Hello to all, thanks for the help.
I'll reply one by one.
-Acesa went out of production slowly, first, with the creation of "Herramientas eurotools" (Acesa, Palmera, Irimo and Irazola), and then with the integration into SNA Europe. This group of brands were just a bunch of factories in poor economic condition and that's why Snap-on can bought them. Progressive introduction of other brands of the group, such as bahco, erases the local brand, but not the factory. For example:
Acesa (one of the most prominent and biggest of spain) still makes adjustable wrenches for the SNA-Group here in Vitoria. they even make the Snap-on branded one, and for europe the same tool is branded bahco. The Bahco branded screwdrivers are made in the old IRAZOLA factory. Palmera was simply shut down and Irimo also, but they mantain a line of chinese made tools, only because Irimo was in Spain like HAZET in Germany or Snap-on in USA.
-Grip-on is an independent brand, but most of the sales are for third countries.
-If you see an adjustable wrench made in spain, and not from SNA group of brands, is 100% a Irega. we're very proud of them, they're all over the world and the factory ONLY makes adjustable wrenches. Take care of them
These four dead dinosaurs were the biggest, but they're some more still producing: Bianditz, Super-Ego, Zubi-ondo, Alvis (my favourite screwdrivers), Ega-master...
To finish this biblic text, I want to say that maybe my country is not very known for tool making, but, we are very proud of our manufacturing, and if you own a spanish tool, remember the people that made them, the concern about quality, because that was all needed in that times, Quality.
