The berachah on immersing a utensil

Hi,

One who is immersing a single utensil recites a berachah beforehand, "על טבילת כלי, al tevilat keli, on the immersion of a utensil."

One who is immersing multiple utensils, without interruption between them, recites a berachah beforehand, "על טבילת כלים, al tevilat kelim, on the immersion of utensils."

(Shulchan Aruch Yoreh Deah 120:3)

Have a great day,
Mordechai
