This is definitely longer than a standard hero saber. If you have a ROTS saber on hand, try grabbing it with both hands, you won't be able to see the emitter, grenade and booster. If Ewan's hands are anything like mine, and I have relatively small hands. The saber would have to be at least 3.5" longer than the hero
It was shortly after that figure came out that everyone suddenly “saw” a stand alone ObiWan story between trilogies. I know it had that effect on me! I like to think it was the inspiration so it’s cool they pay homage to it. Too bad he didn’t have both sabers on his belt!
