A Citrus Reamer is a small kitchen utensil used to extract the juice from a lemon
or other small citrus fruit
To use a reamer, the user first slices a chosen fruit in half with a knife along its equatorial midsection. Grasping the fruit in one hand and the reamer in the other, the user first pierces the exposed flesh of the fruit with the tip of the reamer blade, then grinds out the inside with a twisting wrist motion until nearly all of the juice is extracted. This dislodges the seeds and some amount of pith, so the juice must generally be strained before use.
