Jan,
Outstanding post. We share a love of languages. I have occasionally looked at some of the Tormek sites in different languages. This situation makes me aware that I need to do more exploring. Incidentally, your post also answered my next question. Now that I know the M is for Messer, what do the rest of the third letters stand for? It's all on the German language website.
I still find it puzzling that a Swedish company uses German designations for its jig designations. That may be because of living in a narrowly mostly unilingual country. Multilingual culture is much more interesting.
Here is a followup post from support:
"Hi Ken.
I was a bit stressed when I wrote my answer..my mistake was revealed on the forum.. It is not von, it is fur messer..
I am sorry.. I blame my iPhone..
I am back at work tomorrow and then my spelling should improve.."
My learned friend in support is quite knowledgeable in all technical things Tormek. He just needs a newer iPhone.
