The folding spoon was invented for travelers. The idea would be that it
would be light weight and combine two instruments into one. Sometimes a
spoon and fork are involved. In this case, two different spoon bowls
are involved.
Normally I do not collect these spoons, but I do have one example to
show you.
The mark on this spoon is "800" which indicates that it is most likely
manufactured in Germany or vicinity.
