Help identify please
 

These two things are stored in our family. The picture, in 50-70-ies became grandmother's second husband. In traders on the market in Ukraine, after the war ... He was a good artist, but to determine the origin of this picture could not but feel that this is not that easy. The knife found in the village, where they dug potatoes in the 80 years ... In the village, in Cherkaskoy region of Ukraine. During the war was the military part of the Nazis ... Please'll show the origin of these things. Thank you in advance ...

Pele,
I think that this is a knife for cutting paper. Somehow it little to combat is like. A board interesting, maybe the Dutch or other Western Europe, but the photo of something hard to judge. There are many collectors from Ukraine, maybe from your city is. It must be "alive" look.

As the inscription on the knife:
Citobaryum - is pure barium sulfate.
Merck - the world's oldest pharmaceutical and chemical company, located in Germany.
If course I saw the letter properly:)
