According to Levine's Guide, Jowika is the brand of Weber and Altenbach. They made knives in Germany and Ireland.
From what I have heard, the Irish ones were pretty low quality. I don't know about the German ones...but I suspect they were not a lot better.
At the time of writing, Imperial still ran the Irish plant.
Probably gone, now.
If you want to win an argument, it is best to stick to the truth.....or,at least, provable untruths.
