Does one have to tovel a metal can opener? If no tevilas kelim mikvah is close by, can one use a womans mikvah?
There is no need to toivel a can opener.
A woman’s mikvah can be used, though the blessing must be made outside the mikva area.
Sources: Yoreh De’ah 120:5; Aruch Hashulchan 120:2 explains that only utensils that come into contact with food required tevilah.
