Perhaps the reason for the grim dissolving is that some metals react differently when they come into contact with grim. Weapons like Weiss and Jaune's swords, which are solid constructions, could be made from a type of steel that causes blood to evaporate into that black vapour, where's weapons such as Ruby's, Pyyrah's and Blake's, since they have to fold up into other forms, are made from an other type of metal that reacts just like a normal blade would, with nothing happening after you kill with it.

Then again, we don't know that much about weapon constructing, only that you take any melle weapon in existence (Rapier), put a gun in it (Revolver), then give it a fancy name ( Myrtenaster), and follow it all up with why the hell not? And their you go, instant RWBY weapon.
