Here is a riddle based on the story of goblins "The Golden Horseshoe" that told how it was cut into seven pieces, with a hole the size of a nail in each, and how they turned the seven pieces into talisman necklaces for seven children. It is assumed that, after the first cut, the pieces must be stacked before giving the second, to divide those first pieces again, but the cuts must be straight and the paper cannot be folded.
Once you have solved this simple but interesting puzzle, you can try a harder one. How many pieces can the horseshoe be divided with just two straight cuts?
First make the AB cut to get three pieces, then stack them so that the CD and EF cuts can be made simultaneously.
