Why does obi-wan always use a blue lightsaber?

The wise and noble Jedi Master Obi-Wan Kenobi is one of the most iconic characters in the Star Wars universe. He is known for his skills with a lightsaber, his mastery of the Force, and his dedication to the Jedi Order. Throughout the prequel trilogy, Obi-Wan is shown wielding a lightsaber with a distinct blue plasma blade. But why did he choose to construct his weapon using a blue kyber crystal? Let’s explore some possible reasons behind Obi-Wan’s signature glowing blue blade.

The Significance of Lightsaber Colors

In the Star Wars universe, the color of a Jedi’s lightsaber is deeply symbolic. The kyber crystals that power lightsabers resonate with the Force, and when a Jedi constructs their weapon, they attune themselves to a crystal that aligns with their individual connection to the Force. The traditional colors wielded by Jedi are blue, green, purple, and yellow. Sith typically wield red blades, having made their kyber crystals “bleed” through manipulation with the dark side of the Force.

Color Meaning
Blue Guardianship, reliability, optimized for combat
Green Wisdom, focus on the living Force
Purple Unique crystal affinity, independent thinking
Yellow Harmony between combat and wisdom
Red Corrupted by the dark side

As this table shows, blue kyber crystals represent guardianship, reliability, and a focus on combat skills. This aligns well with Obi-Wan’s fighting style and role as a defender of peace and justice in the galaxy.

Obi-Wan’s Combat Prowess

Throughout the Star Wars prequels, Obi-Wan Kenobi proves himself exceptionally skilled with a lightsaber in combat. He defeats highly trained Sith like Darth Maul and General Grievous, and holds his own against his fallen apprentice Anakin Skywalker. The Jedi Council and other Masters recognize Obi-Wan as one of the Order’s most gifted duelists.

Obi-Wan’s technique relies on classical Form III lightsaber combat, focused on defense and wearing down an opponent’s attacks until a decisive opening appears. This pragmatic, energy-efficient style is optimized for lightsaber-to-lightsaber combat against other Force users. A blue crystal reinforces these characteristics and is well-aligned to Obi-Wan’s fighting strengths.

His Role as a Jedi Guardian

Within the Jedi Order, Knights and Masters choose specialized roles based on their skills and inclinations. Obi-Wan Kenobi serves as a Jedi Guardian, dedicating himself to physical training and perfecting martial skills in order to protect the Republic.

The Jedi path splits into three branches:

  • Guardians – prioritize combat training and military leadership
  • Consulars – focus on negotiation, mediation, and scholarly study
  • Sentinels – balance both approaches as Watchmen of the Order

Guided by Qui-Gon Jinn, Obi-Wan commit himself to the Guardian path from a young age. He trains extensively with lightsabers, starfighters, and military strategy. This enables him to excel as a warrior and general during the Clone Wars. A blue lightsaber crystal supports this choice to follow the Guardian way.

His Master-Padawan Lineage

The Jedi who train a new Knight often have a strong influence on their approach to the Force and construction of a lightsaber. Obi-Wan Kenobi’s Master, Qui-Gon Jinn, wielded a green lightsaber during his long career as a Jedi Consular.

However, Qui-Gon’s own Master, Count Dooku, built a lightsaber with a blue kyber crystal. Dooku later falls to the dark side and takes on the Sith name Darth Tyranus, but during his time as a Jedi he served as a political idealist on the Jedi Council. His pragmatic philosophy influenced the young Qui-Gon, who in turn passed on an appreciation for diplomacy and patience to his Padawan Obi-Wan.

While Obi-Wan does not mimic Qui-Gon’s green blade, he likely draws inspiration from Count Dooku’s preference for a blue lightsaber crystal. Dooku’s combat prowess and dedication to Jedi ideals would have set an example for Obi-Wan in his development as a Guardian.

Balance Between Offense and Defense

The Jedi seek balance in all things, including their approach to combat. Jedi Guardians must walk a fine line between strong offense and impenetrable defense. A blue lightsaber provides Obi-Wan with a balanced fighting style – he can attack and defend with equal adaptability. This versatility served him well in intense duels against the likes of General Grievous and Anakin Skywalker.

Had Obi-Wan chosen a green crystal, he may have favored Form VI, a more offensive style. The blue crystal’s resonance keeps him aligned with the more defensive Form III technique. This equilibrium lets Obi-Wan fully embody the Jedi Code through his skills with a lightsaber.

The Living Force

While Obi-Wan Kenobi follows the path of a Jedi Guardian, he does not neglect developing wisdom and connection the Force. His Master Qui-Gon Jinn embodied the living Force – the energies that surround and bind together all living things. Qui-Gon passed on his understanding of the living Force to Obi-Wan, who continues to reflect on its deeper meanings throughout his life.

A blue lightsaber crystal represents Obi-Wan’s balance between combat training and insight into the living Force. He draws on the living Force to guide his actions as a Jedi Guardian, ensuring that his military powers serve the light side. The blue blade shows Obi-Wan’s spirit of guardian, scholar, and Force mystic combined.


Obi-Wan Kenobi constructed his blue-bladed lightsaber as a Padawan learner under Master Qui-Gon Jinn. He likely drew inspiration from his earlier teacher Count Dooku’s preference for a blue crystal. The color blue aligns with Obi-Wan’s role as a Jedi Guardian and his mastery of Form III lightsaber combat. His techniques blend offense and defense through attunement to the living Force. While individual choice determines a Jedi’s lightsaber crystal, Obi-Wan’s character, training, and philosophy all gravitated him toward the iconic glowing blue blade that defended truth and justice throughout the Clone Wars era.
