[@DarkWolfsDen]

For the "laser sword", when using the first laser: 1. Need a stronger pole for holding the mirror at the top, antenna has too much flex. 2. At the top and bottom use a faceted mirror "cup" that redirects any beams coming into them into the center. 3. Offset the laser emitter slightly off of the bottom cup so laser doesn't get redirected into laser head. By doing this you should be able to get an "infinity mirror" type setup between the two "cups" and any movement in the beam should be redirected towards center of "cup" before being sent to the other cup.
