Twilight Edge

Twilight Edge is Blake Belladonna's primary weapon following the events of the Battle of Argus.

Classified as a High-Frequency Gun Katana (HFGK), Twilight Edge is capable of resonating at extremely high vibrational frequencies, increasing its cutting ability.

Katana
Twilight Edge resembles a katana with a futuristic appearance. The blade itself is forged from a high-carbon steel alloy with a tungsten carbide edge and oxidized to a black coloring. To enhance its durability, the edge of the blade is infused with Dust. As a consequence, the hamon blade pattern glows a bright amber. In the hilt of the blade lies the rechargeable and removable battery pack that powers the weapon. Twilight Edge produces a melodic hum when wielded.

Sheath
Twilight Edge's sheath is given the same oxidation treatment as the blade, giving it a black coloring. The sheath also matches the silhouette of the main blade. The outer edge of the sheath can extend into a sharp blade, reminiscent of Gambol Shroud's cleaver sheath. It also has an extendable carry handle/trigger housing on the outside curve near the opening, allowing the sheath to fire the blade out. Twilight Edge's sheath is usually held to Blake's left side by an electromagnet attached to her belt with the blade edge facing up.

History
Twilight Edge was originally planned as an incremental upgrade for Gambol Shroud. However, during the Battle of Argus, Gambol Shroud was damaged beyond repair after Blake's fight with Adam Taurus. The upgrade plans were repurposed into making a full fledged weapon, now named Twilight Edge, and the development and forging process was expedited. Blake received Twilight Edge during her stay in Atlesia.

Dust Use
Like its predecessor, Twilight Edge utilizes Dust in combat. While it can still be used to modify Blake's Semblance, it is mainly used to increase her blade's potential. Dust is mixed into a solvent, creating an oil that coats Twilight Edge. Blake can apply her Aura into her weapon, generating a blade beam when she swings it. Every time she sheathes her weapon, a fresh coat of Dust oil is applied.
