32. A utensil made partly of metal and partly of plastic or silicone in such a way that its main part is made of metal must be toveled entirely, even the plastic part (ע"פ הרמ"א שם ס"ז). A plastic soup ladle which only has metal on the handle does not require teviloh at all (מו"ר בשו"ת שבט הקהתי ח"ד סי' ר"ה).
33. A schnitzel pounder with a wooden handle and a metal head [the part that touches the chicken] requires teviloh according to the Rama (above, 24) since the head is the main part of the utensil. The teviloh should be without a brochoh (ספר טבילת כלים פי"א סקע"ג ).
34. Covered with paper. A dish which requires teviloh must be toveled even if it is always used with a separation, e.g., baking paper or tinfoil, between the food and the dish. This is because the paper is not considered its own 'dish'; rather, it is viewed as if the food was used with the dish itself (שו"ת מנחת שלמה ח"ב סי' ס"ו אות ה', חלקת בנימין סי' ק"כ ביאורים ד"ה אינם ועוד ).
35. Challoh tray. A wooden challoh tray with a silver sheet covered by a glass surface on which challoh is cut must have all its parts, including the wood, toveled. This is because this type of dish is used when it is assembled; the glass is not meant to be taken off and put back on. Bedi'eved, if one only toveled the glass, it is kosher (ע"פ שו"ת מנח"י ח"ג סי' ע"ז, גליון ח"ח מס' 7 אות ח').
