Chapter 37: 7-9
The Laws of Immersing Utensils
7. When a Jew gives a raw silver or other metals to a gentile craftsman to fashion a utensil, he should immerse it without a blessing. The same law applies when he employs a gentile to repair a vessel with a leak serious enough to prevent it from containing a revi'is of liquid.
8. [Our Sages stated that only Kli Seuda (utensils or vessels used for a meal) must be immersed. This category included:] utensils or vessels which are used for food that can be eaten immediately without any other preparatory steps.
Thus, the iron tools used to prepare matzos and the needle used to sew stuffed foods, and the like , need not be immersed. Nevertheless, a slaughtering knife and, similarly, the knife used to skin an animal must be immersed without a blessing, since these knives can also be used for food that has been cooked. The same law applies to the trays upon which matzos are placed.
A tripod on which pots are placed does not need to be immersed, since the food itself does not touch it. However, a spit used to roast meat should be immersed and a blessing recited.
Some opinions maintain that bottles which are merely used to hold liquids and pour from them into cups, rather than to be drunk from directly, are not considered to be vessels used for a meal and need not be immersed. Others require that they be immersed. Hence, they should be immersed without a blessing.
9. A pepper mill must be immersed because of its metal parts. However, the lower receptacle into which the spices fall need not be immersed, because it is made of wood. (Coffee grinders should be immersed without reciting a blessing.)
