You know, I get so confused when it comes to how lightsabres work. Do you have to press a button, or can you ignite it using the Force? Maybe both? I know in TFA Finn mistakenly pressed the button that adjusts the length of the blade on Luke’s sabre instead of the activation matrix. Fans noticed and I think it was Pablo Hidalgo who admitted it was a mistake. Now I’m studying the fight scene, and Ren doesn’t seem to press anything when he ignites it, so I have to assume he uses the Force.
