A Silver Dagger

The Silver Dagger is an item from the Murder Mystery quest, where it is found at the murder scene. It is used to help gather evidence against the culprit during the quest. In the quest, you must obtain the criminal's fingerprints by using a pot of flour on the dagger, then using flypaper on the dagger. You must do the same with the items belonging to the suspects. Then compare them by using a suspect's fingerprints on the criminal's fingerprint.

When picked up players get the message:
 * "This knife doesn't seem sturdy enough to have killed Lord Sinclair"

Also the below line gets added if the player has already a dagger in their inventory or bank:
 * "You already have the murderweapon" [sic]

Bonuses

 * Unlike in, the dagger can be equipped and gives very small bonuses.
 * It cannot be drop tricked nor bank tricked. If players want to get multiple daggers, however, they can use Telekinetic grab.
