JH Sukuth (#1908) asks:
"I've seen in your report that two DJK's got a custom lightsaber. I wanted to ask if it's usual for DJK to get a customized one (I thought I need higher rank for it) or if it's for some special achievement these two DJK's made."

You are correct that DJK's cannot get custom sabers - however there is a custom saber available only to members of Clan Alvaak, which is available for any Alvaak member DJK and above.

Those two DJK's were both in Alvaak, and were awarded variants of this saber.
