Curved-hilt lightsabers were used by several Jedi Knights of the Galactic Republic since the time of the High Republic Era. Examples of Jedi with curved-hilt lightsabers included Cohmac Vitus' lightsaber and Torban Buck's lightsaber.
According to legend, the sickle-bladed lightsaber was a specialized variant of lightsaber which was wielded by the Sith Lord Darth Noctyss. Unlike more traditional lightsabers, this variant featured a curved blade, making it resemble a metal scimitar.
Count Dooku's red-bladed lightsaber was an elegant weapon befitting a refined man. Its gracefully curved hilt let Dooku slash and lunge with greater precision. Dooku defeated Obi-Wan Kenobi and Anakin Skywalker in a lightsaber duel on Geonosis before being bested by Yoda.
The use of curved hilts allowed for more precise movements as well as near-perfect flexibility when engaged in lightsaber-to-lightsaber combat. It was also more complex and gave the creator of such a hilt more of a challenge in aligning its crystals, as well as requiring a minor variation in holding the grip.
A scimitar (/ˈsɪmɪtər/ or /ˈsɪmɪtɑːr/) is a single-edged sword with a convex curved blade associated with Middle Eastern, South Asian, or North African cultures.
The curved-hilt lightsaber was a type of lightsaber utilized by the Jedi and the Sith. Its curved hilt design allowed the lightsaber duelist to slash and lunge at their opponent with greater precision. Count Dooku wielded a curved-hilt lightsaber during his time as a Jedi Master and as the Sith Lord Darth Tyranus.
Studying Jedi Archive records, Dooku based his new weapon design after the curved hilts that were standard during the heyday of Form II lightsaber combat. The curve allowed the hilt to fit better into his hand, allowing for superior finesse and precise blade control.
The longsword can hold its own against spears, large two-handed weapons, enemies with shields, and armored opponents. It is extremely effective in attack and defensive movements with quick and powerful slashing and thrusting capabilities.
Historically, the largest disadvantage of the curved blade design is that the blade will wear at a disproportionate rate along the length of the curvature, meaning that the curved blade design would wear through quicker than straight blade design.
The Katana (14th-16th century) - The katana is a type of Japanese sword known for its distinctive curved blade and long handle. It was used by the samurai class of feudal Japan and is still widely regarded as one of the best swords ever made.
An example of a Jedi swordmaster was Mace Windu, considered as such because he was a master of all forms of lightsaber combat and due to his mastery of Vaapad, which he created.
The Forbidden Forms were forms of lightsaber combat used by the Sith during the Sith Wars. According to the testimonies of the Jedi Cervil the Uncanny, lightwhips—a lightsaber variant with a flexible blade—were used to defend against Sith Lords who utilized the forms.
Black lightsabers are extremely rare in the Star Wars universe, and only a few have been seen on screen. These lightsabers are typically associated with the Dark Side of the Force and wielded by Sith or Dark Jedi.
Form VII is the last known form of lightsaber combat and is known to be the most aggressive. Jedi Master Mace windu is the main Jedi known to use this form of combat because Form VII is the most aggressive and only the most Force-sensitive individuals can execute this form successfully.
At first, Rey primarily fights with a lightsaber the same way she would have with her quarterstaff. However, after studying Luke's Jedi scripture and training with Leia, Rey probably uses Form VI: Niman, a jack-of-all-trades lightsaber form that combines different aspects of Forms I through V.
But forte is not the only word we get from the sword. Conversely, the weakest part of the blade—the part between the middle and the point—is called the foible.
But one of the fiercest and most difficult weapons to use is the ancient whip sword known as the urumi.
At first, the Katana had straight blades, but as time passed, these received curves due to their efficiency in battle. Since the Katana are slicing weapons, its blades are made curved to execute a better cutting motion.
The Roman Gladius, most of the known world
This makes our list for sheer longevity. The gladius cut out an empire and policed it for 800 years. According to some historians, the design didn't even originate with Rome.
The Three Swords Style (三刀流, Santōryū) is a style of sword fighting that deals with the wielding of three Katana's; one in each hand and one in the mouth.
The longsword is a longer, heavier sword with more stopping power, while the katana is a shorter, lighter sword with a stronger cutting edge.
Bottom line, Dooku never considered himself a Sith. And he wasn't; he was a man looking to change the galaxy in a way the Jedi were unwilling to try. And that is why he joined the Sith and became Darth Sidious' apprentice, Darth Tyrannus. When Dooku became Sidious's apprentice, he was already an elderly man.
Dooku belonged to the aristocracy, and his weapon reflected an older, more chivalric style than the Jedi he faced. It also reflected his status as the head of the Separatists: the lightsaber looked far more ceremonial than practical, suggesting that he himself did not face combat nearly as much as the Jedi did.
