The Death Star's weapon was made with kyber crystals, the same material used to make lightsabers.

How many lightsabers could be made with the quantity of kyber crystals that were used to create the Death Star I?

    Enough to make at least a dozen sequels... – Machavity Jul 22 '17 at 15:49

    Just one, but it would be really big. – RichS Jul 23 '17 at 5:15

The first Death Star contained multiple large kyber crystals. We can see what they look like in this still from the unfinished episode Star wars: Clone Wars - In Search of the Crystal

enter image description here

Assuming it has 8 in total (one for each energy beam) and that they're each as large as the one that Obi-Wan and Anakin intercepted (about 6ft x 4ft x 4ft), we can make some calculations.


A kyber crystal shard needs to be about 1 inch x 1/3 inch x 1/3 inch to use in a lightsaber or approximately 0.00000147 cubic meters. Assuming the larger crystals can be subdivided into individual crystals without losing much material, the answer is that a crystal that's 2.7 cubic meters could make around 1.8 million lightsabers.

Multiplied by eight, you could make something like 14 million lightsabers from the crystals used in the Death Star I.

    Thank you and +1 for answering at the level on which the question was asked. I have long been curious about this question. I do not know why others down voted the OP. – CodeMed Jul 22 '17 at 10:38

    @CodeMed - It's the sort of question that can seem (to the untrained eye) unanswerable and slightly nonsensical. Luckily, the nice people at LucasFilm have given us more than enough technical detail to answer these sorts of questions. – Valorum Jul 22 '17 at 10:39

    @CodeMed - Note that the downvotes have been dramatically outweighed now. Don't be disheartened by the occasional nay-sayer. Keep asking quality questions and you'll get plenty of +1's – Valorum Jul 22 '17 at 21:11

    Deduct probably around a million lightsabers due to packing efficiency and/or wastage issues. – aroth Jul 23 '17 at 6:58

    @aroth - If your men are having problems cutting that crystal, perhaps I can find new ways to motivate them... – Valorum Jul 23 '17 at 8:57
