The PK-07 Combat Knife, nicknamed the Plasma Dagger, was a human designed close combat weapon. It was based off the Type-1 Energy Sword used by the Covenant.

Design
The PK-07 was designed from back-engineered Covenant energy swords. In its deactivated state it was a bulky cylindrical baton eight inches long and four inches in diameter. It consisted of a polymer cylinder containing a power source, plasma generator, and magnetic field generator for shaping the plasma "blade." When activated the plasma extended five inches, creating a cutting edge.

The device could be stored in a specially designed sheath that would recharge the battery if connected to an external power source, or a MJOLNIR nuclear energy pack. A deadman's switch near the projector would keep the weapon deactivated in the sheath, and could be used to automatically activate it upon drawing.

Usage
Like it's predecessor the PK-07 was designed for close combat with an enemy, but unlike the ceremonial and revered energy sword the PK-07 was practical despite it's bulk as a last-ditch weapon. Also unlike the energy sword the PK-07's battery was drained continuously during usage, meaning it had a limited lifespan in combat for regular Marines, although Spartans could connect the sheath to their armor's power pack to recharge the knife. Although plasma knives wouldn't go through each other, knife fighting was not recommended with this weapon.

Much like wounds inflicted by plasma swords, the PK-07 would cauterize internal organs and cause massive trauma due to high heat. A wound to vital areas would often be fatal, and as a limb could be severed by the blade a blow to any of the extremities could potentially be crippling and scarring.
