Yoda's lightsaber

Yoda's lightsaber was a lightsaber constructed and wielded by Yoda, last Grand Master of the Jedi High Council. In keeping with its owner's stature, the green-bladed weapon had a shorter-than-average hilt and shorter blade.

Characteristics
What made Yoda's lightsaber was its scaled-down size. Aside from that particularity, the weapon had a simple design, consisting of a studded chrome handle with black trim and an emitter shroud. It contained a kyber crystal that put forth a bright green plasma blade.

History
Like many Jedi did for hundreds of years, Yoda built his lightsaber under the aegis of Professor Huyang, an architect droid who had been with the Order since its nascent days. As a first step, Yoda managed to acquire a kyber crystal from the icy caverns of Ilum, a mission that proved to be very eventful.

The lightsaber was put to good use on Geonosis, when Yoda was forced to confront his former apprentice Darth Tyranus while the first battle of the Clone Wars was being fought outside.

In the three years of the Clone Wars, the green-bladed saber served its master well on multiple occasions. However, Yoda eventually lost his weapon when he dueled the Dark Lord of the Sith Darth Sidious in the Senate Building. When Sidious unleashed bolts of energy to disarm him, the Jedi Master lost his lightsaber, which fell to the ground below.
