Wise's Tongue Depressor This is a foldable tongue depressor, consisting of two perforated sections connected by a hinge. One section is marked with ‘C.S.H.E.’ on the exterior, while the other displays a circled ‘F’ symbol on the interior. Both sections are labeled with ‘chrome plate’ and the number ‘14’ near the hinge. A tongue depressor is utilized to hold down the tongue, enabling a clear view for the examination of the throat and mouth. 1925-1975
