Hello Saberland,
Did you guys know the myth behind the red crystals?
The red, or synthetic crystals (although synthetic crystals can in fact be any color) actually had the ability to 'break the blade' of the opposing saber in combat.
Here is the quote from the Star Wars wiki:
In fact, synth-crystal blades were so powerful that they had the rare potential to "break the blade" of standard lightsabers by overloading the energy matrix and instantly burning out the other lightsaber. Though this happened extremely rarely, it was a known and frightening possibility in combat.
My belief is, the probability of this happening is so rare, that it probably takes place less than a million-to-one times a synthetic crystal saber clashes against a natural crystal saber... but... this is one of those times:
