Keilim 25:6-7
Keilim 25:6
Regarding the bases, rims, handles and hangers of utensils that have receptacles onto which (ritually impure) liquids fell, one need merely dry them and they remain clean. But regarding any other vessel [that can’t hold pomegranates*] that doesn’t have separate rules for its outside and its inside, if (ritually impure) liquids fall onto any part of it, the whole thing is rendered impure. If the exterior of a utensil contracts impurity from a liquid, the exterior is unclean but the interior, rim, handles and hanger remain pure; if the interior contracts impurity, the entire utensil is rendered impure.

Keilim 25:7
All utensils have different rules for their outsides and their insides, as well as for their finger-holds. Rabbi Tarfon says that the separate rule for finger-holds only applies to a large wood kneading trough; Rabbi Akiva says that it only applies to cups. Rabbi Meir says that the difference between the exterior and the finger-holds applies to both ritually unclean and ritually clean hands, while Rabbi Yosi says that the distinction was only stated regarding ritually clean hands.
