Crysknife
the sacred blade of the Fremen
The crysknife was a knife made from the tooth of a sandworm, the primary weapon of the Fremen of Arrakis. Milky white and double-edged, it was sacred to its bearers and could not be sheathed once drawn until it had drawn blood.
A crysknife was a knife made from a tooth of the sandworms of Arrakis, and it served as the primary weapon of choice for the native Fremen. Sacred to its bearers, much tradition surrounded the blade. Frank Herbert's Dune introduces it when the housekeeper Mapes gives one to Lady Jessica. (Dune; Dune (appendix))
Description#
The crysknife was curved and double-edged like the kindjal, its blade some twenty centimeters long, milky white and iridescent, and fixed to a black handle with deep finger ridges below a slim ring that stood in place of a typical shearing guard. The blade was extremely sharp, and it typically glowed with its own faint light, reflecting ambient light in multiple directions. The tip of a crysknife was commonly poisoned, with an unnamed toxin residing in the tooth's former nerve channel. This poison was potent and fast-acting, as demonstrated when Leto Atreides II and Ghanima slew Laza tigers. (Dune; Children of Dune)
Crysknives came in two forms. The unfixed blade gradually disintegrated unless kept near the electrical field of a human body. The fixed blade was treated so that it could be placed in storage without disintegrating. (Dune (appendix))
Tradition and ritual#
The crysknife was sacred to the Fremen, and much tradition surrounded it. Once drawn, the blade could not be sheathed again until it had drawn blood. It was also forbidden for any outsider to lay eyes on an unsheathed crysknife and then leave Arrakis alive without first being cleansed through an elaborate ritual. (Dune)

Followed from this entry
Arrakis
Arrakis, known as Dune and later as Rakis, was a harsh desert world in the Canopus system and the only natural source of the spice melange. Home to the Fremen and the sandworms, it became the seat of the Atreides empire and the center of the known universe.
Fremen
The Fremen were a culture of humans descended from the Zensunni Wanderers who made the desert planet Arrakis their home. Hardened by water scarcity and generations of persecution, they became the finest fighters in the Known Universe and the foot soldiers of Paul Atreides and his jihad.
Leto Atreides II
Leto Atreides II was the third and final ruler of the Atreides Empire and its first and only God Emperor. The pre-born son of Paul Muad'Dib, he bonded with a colony of sandtrout to gain near-immortality and ruled mankind for thirty five hundred years to set humanity upon the Golden Path.
Sandworm
The sandworm was the colossal autotrophic animal of the deserts of Arrakis, honored by the Fremen as Shai-Hulud and feared across the Imperium. As the central organism in the lifecycle that produced the spice melange, it shaped the economy, religion, and history of the known universe.

Maula pistol: the Fremen poison-dart gun of Dune
The maula pistol is a spring-loaded gun that fires poison darts, with a range of about forty metres. It is a small detail in Frank Herbert's Dune, but it makes sense on Arrakis, where shields draw sandworms and an old-fashioned dart gun still kills.
Stilltent: the Fremen water-saving tent of Dune
A stilltent is a small sealed tent that catches the moisture its occupants breathe out and turns it back into drinking water. It is the stillsuit's shelter-sized cousin, and in Dune it is where Paul Atreides first sees his future.

The Emperor's Blade was a jewel hilted dagger handed down from Emperor to Emperor of House Corrino.

Jamis
Jamis was a fierce Fremen warrior of Sietch Tabr who challenged the young Paul Atreides to ritual combat when Paul and his mother first sought sanctuary among the Fremen. His death won Paul his sietch name and his place among the tribe.
Lisan al-Gaib: Meaning of the Fremen Prophecy in Dune
Lisan al-Gaib means "the Voice from the Outer World", the off-world prophet of Fremen legend. The Bene Gesserit planted the prophecy on Arrakis centuries before Paul Atreides arrived, and Paul and Jessica used it to survive among the Fremen.

Projectile weapons: the old guns of the Imperium
Projectile weapons, firing miniaturised poisoned needles, bolts and darts, were the standard armament of the House Troopers and the militaries of the Imperium.

Shadout Mapes
