Okay, I know, it's not a SAK, but a German knife (is it?) for the Dutch PTT (Post, Telegraaf & Telefonie). The PTT was a governmental company responsible for the postal, telegraph and telephone services.
The tool is dated 1986.
It is not in my possession. It is being offered for sale on the internet.
Does anybody know what kind of tool/knife this is?? What's the purpose of it?
