I'm glad you liked them!
As for your questions, the hands are NOT gold, they are black, like a regular PAM.
The plexy on the edges are i would say 90 degrees, so not rounded as you say. And the piece does feel lighter than i had expected it to be, all due to the weight saving titanium used, and of course the plexy.
As for the case, I am not sure if it is made of teakwood or not, and the corners are all 90 degrees.
Cheers!
