Through a protoss generating psionic energy, psi-blade focusers[1] mounted on forearm units contain[2] and channel this energy, said units being located on power[3] and light armor suits,[4] used by zealots[3] and high templar respectively.[4]ExecutorTassadar was able to channel his psionic powers into blades without the need for forearm units, as well as extend the length of his psionic blade become whip-like and hit distant targets.[2] Psionic blades would cauterize as they cut, making combat among protoss generally bloodless.[5]
Psi-blades are incandescent,[1] and are usually of a blue-white color.[2] Psi-blades can cut through almost any material regardless of density,[6] though can be parried by other psi-blades[7] and warp blades.[8] Over time, the Khalai have further refined psi-blade focuser construction, allowing psi-blades to increase in power as a zealot's fury mounts in the heat of battle.[1]
The Dark Templar have further refined psi blades into much more powerful warp blades[9] through infusing them with both Void energy and their burgeoning psionic power.[10] After the severing of his nerve cords, Artanis demonstrated the ability to wield a psi-blade and warp blade in tandem.[8]
After the fall of Aiur, some Khalai protoss adopted the way of the Nerazim and returned to the planet to wage a secret war against the zerg. These avengers wielded psionic scythes, modified versions of psionic blades.[11]
The Tal'darim possess red psi-blades, referred to as bane blades,[11] which are pure Void energy drawn from Amon's realm, as apposed to pure psionic energy like Khalai protoss's psionic blades or a mixture of both Void and psionics like the Dark Templar's Warp blades. Ancient Tal'darim legends speak of masters who could use them to tear planets in half.[17] Khalai protoss possessed by Amon, including Artanis[18] and Selendis,[19] were able to manifest red psi-blades, as could Emil Narud.[20] The Tal'darim under Narud's command at Skygeirr Station wielded psi-blades of a blue-white color though,[21] as did the Tal'darim under Executor Nyon.[22]
Gestalt soldiers of Project Gestalt, which were terran/protoss hybrids, demonstrated the ability to use psionic blades.[24]
The monomolecular blade utilizes its wielder's psionic energy to hone an edge that has been sharpened to a microscopic degree, allowing it to cut through both physical armor and energy shields.[25]

"They [the protoss] had their armor, they had their honor, and they had their psi-blades."
- Samwise Didier, commenting on the early development of the protoss(src)
Psi-blades were conceptualized early in the development of StarCraft. One of the touchstones of the protoss was the idea of "space samurai." This applied to psi-blades, namely the idea that as no samurai would be found without their sword, psi-blades would similarly be integral to the protoss. Inspiration was also taken from other light-based sword weapons that were well established in sci-fi.[27]
A psi-blade prop was created by Scrap Shop Props and Henwench. The work was spotlighted by Blizzard.[29]
StarCraft II[]
In StarCraft II, psi-blades are colored in accordance with player color in multiplayer games. Some fans reacted negatively, but a compromise was never reached.[30]
Exceptions within the campaigns of StarCraft II are the yellow psi-blades of Karass's zealots,[31] and the green psi-blades of the Zhakul Guardians.[12] In the case of the Guardians their team color (black, not available in multiplayer) is separate from their psi-blade color.
The ghost model has an unused animation for using a psi blade.[32]
Concept art was created for a terran scout, which would utilize protoss psi blades.[33]
