Reamer is another term for juicer. It refers to a hand-operated tool that is typically used to extract juice from citrus fruits, such as oranges or lemons. This kitchen utensil has a fluted cone-shaped reaming end that is twisted into and against the meat of the fruit to release the juice.

It is available in hard plastic, wood, or metal. The hand reamer is primarily made to extract smaller volumes of juice from fruits during food preparation.
