I found this at a flea marked about 15 years ago and it just seemed cool.
It is pretty beefy and it was apparently hand made with a nice level of skill.
The only markings are the number 8 stamped in many places.
Started looking for more like it and, so far, no luck.
But I did drag a couple hundred others home in the meantime.
I have found others with the sort of 'chevron' or whatever the design element is near the head, but nothing like that first one.
(Wrenches are like some other special thing. The only ones you think about are the first one and the next one!)
Eberhard, Hershel, Champion, and others, as well as the Diamond K Kraeuter are all multiplying in my garage.
