Darth Tyrannus' Lightsaber, mini saber replica by Master Replicas
This has the distinction of being one of the few items I have in a display case, and therefore the only item so far featured in the Pic of the Day that I haven't had to dust before taking the picture.
Master Replicas made some fine prop replicas back when they had the Star Wars license. Specifically, they made fullscale lightsaber hilts and helmets. I always wished I could get into the saber hilts, sure they're just glorified paperweights, but they're VERY glorified. Supremely constructed and absolutely accurate, but oh so expensive.
Luckily, they foresaw that not everyone would be able to collect these pieces, and so made a smaller scaled line of saber hilts. These mini sabers are .45 scale, which works out quite nice both in price and size (size is important, as the fullscale hilts do take up a lot of room, and the helmets are much, much worse. I believe they released more mini sabers than full size sabers, but I could be wrong.
I have most of the mini sabers, but do have a couple of glaring holes in my collection, but I also have a couple of the much harder to find hilts, like Obi-Wan's saber from Attack of the Clones, but that's a picture for another day. I do wish they would have started the mini helmets sooner, so I could have bought more of them before I instituted tighter constraints on my spending.
Remember Kids: It is obvious that this contest cannot be decided by our knowledge of the Force... but by our skills with a lightsaber.
