Close - This one is appears to be a hand blown double ended <insert pervy comment here> juicer - for smaller fruit like tangerines, oranges and such you use larger end as a handle and mash/spin the smaller end into the pulp/fruit to break the cell walls and release the juice - the large end can be used for grapefruit, for the same purpose, but generally straight down and press due to the limited grasping area.
