Crackle-saber

Crackle-sabers were weapons similar to Lightsabers, but instead of making the normal, calming hum, it made crackling noises (like Kylo Ren's saber)

Blades:
Some crackle-sabers had one blade, but others two blades on one side, or like the Cross-saber. Rare crackle-sabers had three blades like the Cross-saber, though looks similar to the Sai.
