The BM001 Razor is a modified version of the Bullseye which has been tailored to suit a human user. Because of this, it can use the same ammunition as the Bullseye, which is obviously the main weapon of Hybrids. Although its rate of fire isn't the quickest, it is extremely potent and can cause considerable amounts of damage.
The BM001 Razor is arguably one of the more powerful weapons in the game due to its secondary fire mode. It allows the user to charge all of the remaining ammo left in the clip into a concentrated burst (called the Homing Energy Blade) which can hit multiple enemies and rebound off of walls.
Although the Razor is generally good against the majority of enemies found within the game, it is especially effective against machine based enemies, such as Drones.
