The degree of the curve at the top of the hilt in relation to the hand holds was the important factor. The curve at the bottom of the hilt (if present) only affected electronics and power core placement. The bottom curvature on many lightsabers was mostly ornamental.
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, requiring a minor variation in holding the grip. Curved hilts needed to be held more in the palm, farther away from the fingertips. The hilt's curvature also gave the wielder more power when delivering overhand strikes and would change the angle of the attacks by the merest fraction of a degree; this was usually just enough to confuse and disorient an unsuspecting opponent, as evident when Valenthyne Farfalla fought and lost to Darth Bane in the Duel on Tython, and again when Anakin Skywalker and Obi-Wan Kenobi quickly lost to Count Dooku in their duel on Geonosis.
Some techniques were more difficult when using a curved hilt, but many others became far more effective. This hilt design was not limited to Form II; its advantages in dueling carried over to every form including Form V, as in the case of Darth Bane. Unfortunately, one major side effect of wielding a curved-hilt lightsaber was that they were more difficult to use in blaster-bolt deflection. This, coupled with Form II's weakness in this area, made a Makashi user wielding a curved hilt particularly vulnerable to blasterfire.
In Star Wars: Galaxies, players of the Jedi class could find a lightsaber hilt called the "Old Republic Hilt" on Mustafar, indicating that the curved hilt was a possibly common design during the days of the Old Republic. This hilt is one of the more powerful lightsaber hilts in the game, and it resembles a curved-hilt saber.
