3 questions

Hello,

I have 3 questions:

1. What is the difference between FIE saber blades and a non FIE
blades?
2. What is the difference between all the blades? (what is Super
blade? ,what is Bluestar blade? ect`).
3. I have an old 3 weapon box (allstar universal signaling unit 'Club'
(foil, epée, and saber)).
In the past I used it for all 3 weapons including Saber – but that was
at the time that electric saber was working with sensors.
As you probably know we don't use electric Sabers with sensors anymore
..
Can I use the old signaling unit?
Is there any way to use it with the new Saber system?

Best Regards,

Ram Freedman
