I always thought she received it from Master Piell after his death escaping the citadel during the clone wars and then further customized and adapted them
Im not sure what to think about dual sabers, they usually are used in a too offensive way, it limits your capacity of handling the hilt since you are not using it with both hands on 1 saber to do more precise and stronger movements, specially when you are dueling instead of fighting multiple targets, i guess jar'kai gives you more offensive power against armies but a lack of precision and strength in dueling. Personally i wouldn't use duals.
