Yes! Let's talk clamp covers!
I recently spoke with two different ex-employees from the no longer existing company Propshop, who made the lightsaber props for TFA (and were reused for TLJ). These guys didn't know each other, because there were many people at work.
I also held and studied an unofficial resin cast from the hero Graflex saber (Finn's) and I was able to study all the fine details and the clamp cover from that.
The original saber had a clamp cover that was photo etched, with the outer edges and slot fully etched and the inner grooves half etched, making them not go through completely. The photo etched details are sharp, like laser cutting, but with the option to have closed slots as grooves.
I heard that the Propshop used photo etching more often in their process which they outsourced to an English company.
Their clamp covers did not have the fixation tabs and were pre-bending and very hard to put on. My design with the tabs behind the clamp bars seems like a smart move.
So, my next batch of clamp covers will be made like this and will replace both the pressed and laser cut versions. Now I know how these were originally made, there's no point in selling the lesser versions.
