Lighthammer

The Lighthammer was a Lightsaber with a long metal hilt (about five and a half feet, or 1.7 meters long)with a mass of energy focused at the end. Due to the heavy weight of the hilt, which weighed 277.2 pounds (Europe 126 kilograms), only individuals with remarkable strength could weild them proficiently (such individuals were occasionally found in the human species, but more often found in Gamorreans, Wookiees, Talz, etc.). Although the hilt was large, the power crystal was only about three quarters the size of that of an ordinary lightsaber, leaving the hammer with to little energy to sever a body part. To compensate for this, the hammer had a system throughout the entire hilt (which accounted for much of the hammer's weight) that would generate small explosions with each successful hilt. These explosions could be so powerful, that a hard hit from one could destroy a small starfighter. Because of the attack style and design of the weapon, the lighthammer was rarely used by Jedi, who generally thought of it as being "a weapon designed for agression".

History
Ironically, the lighthammer was not originally invented with the intent of being used in combat. It was made by a Gray Jedi lightsaber hobbyist. It did not have the explosion system when it was invented. When the inventor was killed by a Dinharanalea Dark Jedi, it was taken and modified. It eventually became the main weapon used by the Dinharanalea army. However, due to the size of the Dinharanalean army (the species was near extinction), the mighty warriors were almost unheard of. A few Lighthammers had been crafted and used by creatures outside Dinharanal, but very few knew the technique for crafting them.
