Miracle egg opener

This morning, Saint Nicolas had a surprise for me: an egg opener.

Everybody was curious to see what was in the box and how it works.

As you can see it's pretty simple and all you have to do is put on the egg...

... lift the steel ball and let go which cracks the egg...

... then with your knife you open the egg. 

As simple as that and unbelievably perfect. Just the right size for my mouillettes (bread sticks to dip into the egg)

Wolfram tried as well and got the same results. 

Danke schön Saint Nicolas Christian :)
