This is an actual forged blade, that has a power bound to it, in this case Logrus Power. The most known (and named) blade of this type is name “Reef” or “Reefs” and is held and wielded by Raven.

This is opposed to a blade made from a previously existing Logrus Master (someone in an equivalent role to Suhuy) (as Caine’s blade “Shoals” apparently was), or a blade curdled out of Logrus (or Serpent) energy, as Ilk’s unnamed blade seems to be.
