I have a cutlery set that came with 7 teaspoons. Six of them are the same, but one is different. In the following image I have three of the six on the left side of the picture and the different one on the right.
Unfortunately I don't have the box the set came in, but on the back of all the cutlery it says "justinus edelstahl 18-10". I was unable to find information online about what teaspoon that is.
What is the one on the right used for? Why does it have a flat tip? And why was there only one in the set?
The set was for 6 people, so I have 6 spoons, 6 knifes, 6 forks, 6 little forks, 6 (normal) teaspoons, a few other things, and this strange teaspoon. It had its own special place in the set, so it is not a defect. And it doesn't look cut or chopped or smoothed. It was created like that. It definitely had its purpose.
