The statement "Barukh shem k'vod" is uttered so as to avoid taking God's name in vain while reciting a blessing over one of these objects.

The letter shin molded on one of these objects combines with two (*) knots shaped as the letters dalet and yud on two of them, to form the word Shaddai, one of the names of God. One of these objects contains one large compartment in which a single strip containing four passages can be deposited, whereas in the other, there is a slot for each of those passages. For 10 points, name these parchment-filled black leather boxes attached to the upper arm and forehead, worn by Jewish men during morning prayers.
