For all the brilliant CGI shots in RotS (which easily had the best CGI of the Saga), somehow the practical effects fall incredibly short. How is it that whoever was the prop master for RotS could not be capable of matching up the RotS saber hilts to their ANH counterparts? There is only a superficial resemblance. The shape of the handgrips are wrong, the activator matrices are completely wrong (the Skywalker RotS hilt having closer resemblance to the circuit board that Luke would replace the bubble tape with), the rims around the activator matrices are wrong, and the blade emitter on the Skywalker are two entirely different shapes. From a distance, they (like most lightsabers) look the same, but on closer inspection they are nearly entirely different in design. In all honesty here, Kit Fisto's lightsaber looks closer to Eeth Koth's than Anakin's RotS hilt does to Luke's ANH one. Frankly, if a prop master brought me the Anakin saber we see on screen in RotS, I would have told him to go back and try again. For things like the color differences between the top of the hilt in Obi-Wan's lightsaber, and the faded metal VS the shiny new chrome metal I can understand as an aging thing, but the design of the hilts are so different it looks like that during the twenty years Ben spent in that hut, he took the two lightsabers, stripped them down, then rebuilt them from scratch. So, is there an explanation for these discrepancies? Is there any canonical record (even EU) of Obi-Wan modifying the two hilts between RotS and ANH?
