The first is a knife. The hilt is beautifully designed like a rose, with a stem large enough to be a real hilt, and a distinct lack of thorns. It leads up into a rose shaped crossguard, and is tipped in a red blade, the color of a rose's petal. One who grabs it will know that the length and weight of the blade can be adjusted as the user wishes... as long as it is fed with blood.
The other weapon is what appears to be a recurve bow, already strung. Except for the grip, it's green and covered in thorns, and resonates with more than a small amount of power. The one who receives this boon will know that any arrow fired from it will slowly sap the blood from it's target as long as it's embedded in the enemy.
