Looks like a Soap dish to me
.

I have seen flambe' pan`s just like this it`s to use at Table by a a flambe`chef

I am pretty sure it`s a Sugar Saw, up until the start of the 20th century Sugar was sold as a "sugar loaf" you had to cut lumps off it
.

You were sold a wine taster as you first suggested to give it, it`s proper name which is a "Tastevin" the hole in the handle part is for a chain to hang around a Sommeliers neck,
A sommelier is a wine Waiter/Steward it is the typical size and shape
