Aside from the blade of another lightsaber, there were rare materials that could withstand a lightsaber blade, but with varying degrees of success:
* Cortosis, although a rare and expensive metal, was a popular defense against lightsabers. Purified cortosis ore had the ability to momentarily "short out" a lightsaber blade, rendering it inoperable for a brief period of time before the wielder could reactivate it. Cortosis alloy was sturdier than purified cortosis ore, but was only capable of deflecting a lightsaber blade and not deactivating it. One reason why cortosis was so expensive was the need to refine it. Pure, unrefined Cortosis ore was—for unknown reasons—dangerously ionized and anyone who touched it would be killed instantly. There were multiple methods of forging cortosis armor and weapons, each with varying effects.[source?]
* Phrik, was a rare metallic compound that could withstand a lightsaber blade, although unlike cortosis, Phrik did not possess the ability to cause the blade to short out. Phrik was most notably used in the construction of the electrostaffs wielded by General Grievous's MagnaGuards. Other notable uses of Phrik included elements of Palpatine's lightsaber and Dark Trooper armor.
A tikulini's skin could withstand a lightsaber strike
* Darkswords were an ancient type of sword made from a special material that could parry lightsabers. Unlike cortosis, this material did not possess the ability to temporarily deactivate a lightsaber blade it made contact with.
* Armorweave was a cloth said to give some resistance to lightsabers, although the protection the reinforced material afforded was limited.
* Sith Alchemy was employed during the eras of the first Sith Empire to augment the properties of metals so as to counter the seemingly unstoppable lightsaber. The Sith also made use of such elements as cortosis in the forging of their Sith swords. After the original Sith Empire, the most notorious use of Sith alchemy was in the construction and reinforcement of Darth Vader's armor.
* Mandalorian iron: A metal found on the planet Mandalore—known as beskar in the Mandalorian language—Mandalorian iron could be forged into several configurations to take advantage of its exceptional lightsaber-resistant qualities. Commonly used in the creation of Mandalorian armor or weapons, the metal was also used to construct the door sealing Freedon Nadd's tomb.
* Force Weapon: Weapons imbued with the power of the Force could be used to parry a lightsaber's blade without harm.
* Water: All lightsabers, unless specially made,[14] would short out when they were submerged in water, due to rapid chain reactions and the instant overpowering of water on the blade. In rain, a lightsaber would steam up, but not short out.[15]
* Zillo Beast Skin:A Zillo Beast skin was both lightsaber proof and blaster proof. It showed its affectivness when Anakin Skywalker tried to attack the beast.
Other counteracting materials existed in the galaxy, such as various energy shields. Some animals, such as lava dragons, were possessed of natural armor that reflected the blade[source?]. Superconductive materials (e.g., Ultrachrome, Quantum Armor) deflect lightsaber strikes.[16] The skin of the Tikulini worms of Jazbina was able to withstand a lightsaber strikes.[17]
