The dagger is indeed mentioned in the comic. On the penultimate page of "Truth and Daggers", Belle says to Rumple, "Samuel had a map to this castle and a drawing of your Dark One Dagger [sic]. (...) He came here to seize your dagger so he could control you with it. He and his men intended to use you to plunder the Enchanted Forest." We even see a drawing of the dagger among Samuel's things, which says "Rumplestiltskin's dagger".
