Apple/Potato Corer

My lovely wife was manhandling some potatoes the other night to make some potato bombs. In the process of coring the potatoes she broke our corer. It was only the second time using it so it wasn't an old piece. But it must have been a piece.

What would everyone recommend to core the potatoes, not making potato bombs is not an option. Anyone know of anything that is rugged enough to stand up to my wife?

That's very similar to the one my wife broke
