This is a KRSabers "Marrok" carried by the character in the Ahsoka series in season 1. Marrok's character is an inquisitor and his saber reflects that with the giant ring.
The ring aspect can easily be locked in place via two set screws in either the closed or open position. Alternatively, these rings can also remain unlocked for easy folding.
The saber is installed with a single proffieboard, but still has the ability to control each blade independently.
The 3 buttons work so that the two buttons closest to each blade work independently for that side of the saber, while the center button will control both sides.
Components used:
Proffieboard v3.9
21700 hard wired battery
2.1mm recharge port
28mm speaker
high amp killswitch
3 tactile switches
You can choose to add two 28" blades with the order.
No charger included
