Well, I really had to leave, but when there was the thing about the quote, I could'nd stay from finding it:
It in the chapter called "Highprince of war" (or something sounding similar, it's my translation from german to english) and it's in part two of the book ("the luminous storms" or something like this). The quote appears short before Dalinar tells Renarin that he would give a Shardblade and Shardarmor to him. It's (translation^^):
"Dalinar had hard-earned a Shardblade and a Parshendi armor while the first year. He had given both to Elhokar, because he had thought it was very useful for Alethkar and the war."
Edit:
Well, you could say, Elhokar could have given them to one of his bodyguards or warriors, but we know that both are Kholin men - which means that they are Dalinar's men, as Elhokar has no own land and no own army, and his guard is made of Dalinar's men - so it would be more obvious, that Dalinar gave both to one of his on men (guards), to protect the king, if it wasn't for the king himself.
(Well, maybe contraditing my thoughts could be the fact, that Dalinar later told Renarin, that he could give him the Shardblade and the Shardarmor, while no other Highprince gave them to the king - this thought is ambigious to my previous thought/quote, I have to admit).
