A Nox Nyctores, in other words, the Arch Enemy, is a weapon specifically constructed from a Black Beast (a compressed portion of it is made into it's core) to fight the Black Beast. The weapons themselves are capable of recognizing each other through some kind of resonance (for example, the Noxs recognize the ACWs as something similar to themselves). If a Blood-Scythe was a Nox, there would be some reaction from other Noxs or ACWs to it. Also there are only 10 Nox Nyctores mentioned in the series and the Blood-Scythe isn't among them. Aside from the 10th, they were all constructed during the Dark War to fight the Black Beast.

Blood-Scythe might not be a normal weapon, but it doesn't seem to be a Nox Nyctores.
