One long-forgotten Sith lightsaber type would have been the perfect weapon for Obi-Wan Kenobi – but there’s a good reason he’d never use it. Most Jedi choose a lightsaber form that compensates for their weakness; Mace Windu’s Vaapad is designed to channel his inner rage and anger, while Yoda chose the agile Ataru to compensate for his small stature. Obi-Wan Kenobi is an exception, however; he chose Form III, Soresu, simply because its defensive nature appealed to his character.
