Razor's Edge

"As extinction loomed, desperation led the Forerunners to experiment with volatile derivations of hard light. Advanced Suppressor firing fast-moving metastable energy shards. If multiple shards strike a target they will create a "supercombine" explosion."

- In-game description

The Razor's Edge is a special variant of the Z-130 Directed Energy Automatic Weapon that appears in Halo 5: Guardians as a Rare REQ variant of the Suppressor. Its chassis is based on the regular Z-130's except that the main weapon color is now dark gray with orange and turquoise stripes painted around the weapon's main body and grip area.

Background
The Razor's Edge is a named variant of the Z-130 DEAW, modified to fire metastable energy shards similar in operation to the Subanese crystals found in weapons like the needler. Its first use was towards the end of the Forerunner-Flood war, where the Forerunners faced their extinction from the Flood and became desperate, eventually resorting to experimenting with volatile derivations of hard light. These experiments eventually led to the inception of weapons like the Razor's Edge.

In late 2558, the Razor's Edge was integrated into the 's War Games simulations for use by Spartan-IVs.

Halo 5: Guardians
The Razor's Edge, a Rare Level 3 REQ that grants 100 REQ Points when sold, operates exactly identically to a normal Suppressor albeit with the added supercombine functionality of the Needler along with the ability to directly damage heavy armor. However, out of all the supercombine-capable weapons in the game, the Razor's Edge has the tightest supercombine time window, lasting only 0.9 seconds. Six shards are needed for a supercombine explosion. In addition, the Razor's Edge has a lower rate of fire in comparison to the lesser Suppressor models. Despite these drawbacks, the Razor's Edge is the most powerful of the Suppressors, as it has a very high round count (maximum 288) and can deal decent damage to vehicles and heavy armor, even serving as an alternative to the Talon of the Lost if the player is running short on their supply of the latter weapon.

Unlike the other supercombine-capable weapons in the game, the Razor's Edge's supercombine explosions also disintegrate any dead bodies within their blast radius.
