Do I need to immerse wooden utensils?

Hello,

There is no need to immerse them.

Sources: The exemption of wooden utensils from immersion is explained in Shulchan Aruch Yoreh De'ah (Siman 120, Se'if 6) and in the Rema there (Se'if 7). This is also noted in Chochmat Adam (Klal 21, Se'if 1) and in Ben Ish Chai (Year 2, Parashat Matot, Halacha 14).

Best regards,

Hillel Meirs
