A Shardblade is a powerful weapon capable of slicing rock and severing souls.[1][2] A Blade can also be used to cut spheres. People who possess a Shardblade are called Shardbearers; they are each soul-bound to their Blades until death, or until each Blade is willingly relinquished.

Shardblades were devised as imitations of the Honorblades, which were created by Honor for the Heralds to imbue them with Surgebinding skills. The spren on Roshar saw what Honor had done and eventually came up with a way to grant those same Surgebinding powers to people with cracked Spiritwebs by forming a bond with them. At some point in the development of the bond, the spren itself becomes the Shardblade when needed. When those people betrayed their Oaths, the spren died and became the Blades used on Roshar today. Further, as Brandon has said, many Shardblades have names that extend well beyond their original owner.[3]

So, since the original pattern was the Honorblades, Shardblades were built to feel like the Honorblades.[4] Honorblades are not spren, however. Just how Honor created them is not known.

Shardblades are generally associated with Shardplate; a suit of armor that completes the set.


According to legend, the Shardblades were first carried by the Knights Radiant uncounted ages ago. Gifts of their God, granted to allow them to fight horrors of rock and flame, dozens of feet tall, foes whose eyes burned with hatred. The Voidbringers. When your foe had skin as hard as stone itself, steel was useless. Something supernal was required.[1]

After the Recreance, any spren who was in Blade form when the Radiants abandoned their Oaths was frozen into that form. Later, the addition of gemstones allowed the frozen Blades to be bonded after a fashion, so that they could be summoned and dismissed.

Four millennia later, they are regarded as priceless relics. Wars are fought for, and won by them.

Within his visions, Dalinar was shown roughly 300 Shardblades that were abandoned by members of two Radiant orders. Dalinar estimated, at the time of the War of Reckoning, that there were less than 100 Shardblades in all of the world. Alethkar and Jah Keved own some twenty Shardblades each; the rest are spread amongst the weaker nations, including five Shardblades held by the Thaylen royal guards. Selay, and other kingdoms such as Herdaz, have only a single Shardblade apiece. Kharbranth[5] and the Unkalaki people[6] are not known to have any Shardblades.

So far, no amount of fabrial science has even approached the possibility of re-creating Shardblades.[7] However, recent rumors have claimed that Alethi scholars are close to creating new Shardblades.[1]


No two Shardblades are the same,[8] but all Shardblades cut easily through most inanimate matter, so long as the Blade is kept in motion.* They do not cut living flesh; instead the metal fuzzes as it passes through, killing without leaving a mark or spilling blood. It was said that Shardblades sever the soul itself, the only indication of death being that the victim's eyes burn out. Any part of the body that is cut dies instantly. If the Blade touches a man's spine, he dies, eyes burning. If it cuts through the core of a limb it effectively kills that limb, rendering it permanently limp, numb, and useless. A limb severed by a Shardblade needs to be reattached to the soul before it will function again.[9] However, Surgebinders can heal limbs severed by Shardblades by using Stormlight. If a vital organ is struck, it will render that organ useless as well.[1] Once dead, flesh can be cut just like any other object. Also, parts of a living body that are made of non-living tissue such as hair, fingernails, and the shells of beasts are cut normally. A modern interpretation is that Shardblades can only sever nerves.

Shardblades are enormous, yet remarkably light. They were designed to fight foes more formidable than the average man. The large weapons take a great deal of skill to swing properly.[10] There is rarely recoil; landing a blow is said to feel similar to passing the Blade through air. The trick is to control momentum and keep the Blade moving.[11]

A Shardblade can only be blocked by another Shardblade, by Shardplate, or by half-shard shields, though the latter are less effective. Nightblood also may have the capability of blocking a Shardblade.[12]

One knows a Shardblade when one sees it.[13]

A Shardblade can kill a Vessel.[citation needed]


Adolin supposes that just as Ryshadium choose their own riders,[7][14] Shardblades were once spren who chose their own bearers.[14]


A Shardblade is summoned by the Intent of the Shardbearer, willing it into existence, typically dropping into his/her hand extended to the side. The process of summoning takes exactly ten heartbeats. When it materializes, the Blade is typically seen covered in water beads along its length, as if condensed from mist.[1]. However ...

So the more urgent you felt, the sooner you were armed.[15]

So, the summoner's heartrate definitely has something to do with the summoning of his/her Shardblade.

If a Shardbearer lets go of his/her Blade, the weapon reverts to mist, vanishing (unless it had been willed to stay), which was a protection to keep a Blade from being taken by one's enemies; the Blade vanished unless one willed it to stay when releasing it.[2]

Shardbearers are soul-bound to their Blades until death, or until their Blades are willingly relinquished. The process for realignment first requires the new Bearer to simply pick up the Blade. Second, upon acquiring the Blade, it takes five days before the Shardbearer fully bonds to it (and is, otherwise, able to dismiss it). When the Shardbearer dies, the Blade rematerializes next to him/her, allowing anyone else to pick up the Blade and become its new owner.[citation needed]


Wielding a Shardblade with one hand is a challenge, even when one doesn't have to worry about hitting one's own men.[13]


Unbonding a Shardblade is supposed to be a difficult process, requiring concentration and touching its gemstone. Yet that of Dalinar after he bonded with the Stormfather was severed from him in an instant. He could feel it.[16]


Shardblade Concepts
Fan art by quargon[1]

Though each Shardblade is unique, there are in general three types of Shardblades.

The first is the type that is wielded by some Shardbearers in The Way of Kings, Words of Radiance, and Oathbringer, they take ten heartbeats to summon, have a gemstone in the pommel, and can cut through stone easily.  When held by someone bonded to a living spren, screams fill their wielders' heads. Syl mentioned that these types of Shardblades are dead spren and that this is why people who are bonded to living spren hear screams when coming into contact with these Blades.[17]

The second type are those wielded by Knights Radiant; they can be summoned when the spren are ready (instead of taking ten heartbeats as those of dead-spren Shardblades do) and can take any form (i.e., Syl could be transformed into a spear, dagger, halberd, and/or shield during Kaladin's mid-air duel with Szeth).[18] They have the same properties as other Shardblades, but unlike other blades, they glow certain colors from glyphs and symbols on the Blade, and their bearers hear no screams from them. When Knights Radiant wield their blades, they can subconsciously communicate with their spren. (This is also shown during Kaladin's mid-air duel with Szeth in which he, without talking, instructs Syl to morph into different weapons).[18]

  • Wyndle informs Lift that there is a connection between a spren's power, when condensed, and metal.[19]

The last type, with regard to Szeth's (now previous) Blade and Taln's (now previous) Blade, are actually Honorblades. Szeth was never bonded with a spren. Taln was one of the Heralds who wielded an Honorblade, yet lost it in his present madness. (In Words of Radiance, once Dalinar had become a Radiant, he heard the Blade he held screaming, indicating that it was a dead-spren Shardblade.)[16] Honorblades are believed to grant some power over the paired Surges for each Herald (i.e., Jezrien's Blade grants Adhesion and Gravity; Nale's Blade grants Gravity and Division, etc.). These Blades were made by the Almighty himself and give the power of the Radiants to whoever wields them.[17]

"Ten heartbeats, Return to me, you creation of Damnation."


"There is something wrong with your Blade, and with all Blades." She hesitated for just a second. "All but mine. Pattern!"

Shallan to Adolin[18]

"So they're all spren," he said. "Shardblades."

Syl grew solemn.

"Dead spren," Kaladin added.

"Dead," Syl agreed. "Then they live again a little when someone summons them, syncing a heartbeat to their essence."[17]

"We're spren," Syl said. "We're forces. You can't kill us completely."[17]


*According to Brandon, any object that is sufficiently thick but also sufficiently pliable that it's going to press down on a Blade while it's cutting is going to create drag on the Blade.[32]

**Renarin tells his brother that he has to give back the Shardblade that Adolin won for him. When Adolin asks him why, Renarin tells him that it hurts to hold. That it always has. Further, he tells his brother that they - none of them - can use the dead Blades. That it's not right.[14]

Adolin tells Renarin that by right of bestowal, the Blade is his, and he should pick the successor. Renarin then tells his brother that he's given it to the ardents already, for safekeeping.[14]

***Shardblades are made of Investiture; aluminum blocks Investiture.


Reviving a "dead" Shardblade might be so difficult because the layout in which it takes to form itself to someone's Spiritweb is preserved. In order to bring it back to life (at least, the life and sentience of Syl or Pattern), it needs an EXACT copy of the original owner's Spiritweb. Anyone else's Spiritweb layout is going to be different. With Syl this wasn't a problem, as Kaladin's soul was ready to accept her back in. But for a Blade like Sunraiser or Oathbringer, whose owners have likely been dead for millennia ... finding someone with a Spiritweb that would be able to figuratively "fit" them would be beyond difficult.

Also, it has been theorized that Shardblades are stored in the Spiritual Realm when not in use.

Q&A with Brandon[]

Q. If a Shardblade was used on an Awakened object, would it physically harm the object, destroy the Breath, or a combination of the two?

A. You will someday know.[33]

Q. Is there any ramifications to the holder of a Shardblade for using a blade in a manner that it wasn't intended?

A. Depends on the type of Shardblade. (You have seen three different kinds in The Way of Kings.) For most, no. For some, most certainly.[34]

Q. Is it possible then to reawaken a Shardblade if that Blade is wielded by someone who speaks the Oaths of a Knight Radiant?

A. Yes, but it would be extremely difficult. The spren in a Shardblade are not trapped in a state of mid-transformation like the Elantrians. They are stuck in an agony cycle after having a significant portion of their consciousnesses ripped out of them. The Nahel bond is what allows spren to think on [the] material plane and that has been torn away. It would be like having a data jack installed and then having someone come up to your head and rip it out of your head.

Q. You know the sparring guards, for the Shardblade training, the guards they put on the Shardblades. Are they made of aluminum?***

A. So, they are not. Peter will not let me make them made out of aluminum. He's my continuity editor, he keeps me honest. I tried to get them to be aluminum, but there are reasons why they can't be. So we had to make them their own weird little thing, unfortunately. But you could make a sheath out of aluminum for a Shardblade that would work.

He keeps me honest, so it's good, but I did try to fit them in that way.[35]
