This hand tool is used to squeeze half slices or wedges of lemon or lime.
Especially with tea, these tongs are offered together with the lemon slice. The disc is placed between the jaws of the forceps and the arms are pressed closed. The juice flows into the cup through the drain. Usually these pliers are made of metal. Like the lemon reamer, it serves to obtain only a few drops of juice.
