What could this utensil pair be used for?
The handle of the round plastic object feels really distinctive to me. It would clearly work with a normal hammer-like grip, but it also has the thumb-print inviting the user to choke the grip up close and apply lots of force. I'm pretty sure it's for scraping. 

The metal tool is a bit confusing; it looks like it could cut, but it's clearly not a knife. 

After a minute's thought, I'm comfortable guessing that this is a child's pumpkin-carving kit.
