摘要:
A dental tweezers with plastic tweezers main body is disclosed. A weight cavity is disposed on both tweezers arms of the main body. Weight arms of a metal weight are inserted into the weight cavities. A weight seat holds the metal weight in place on the tweezers main body. The metal weight makes the dental tweezers feel heavier and more substantial. After the dental tweezers have been used the metal weight is removed from the main body. The plastic tweezers main body is disposed of and the metal weight is retained for future use in an new plastic tweezers main body. A use indicator of the tweezers main body indicates that the dental tweezers has been used. The use indicator provides easy determination of whether or not the dental tweezers has been previously used.
