I just finished my Tempered Spinal Blades today and love them. Wonderful art, nice glow, and very Engineer-y! I only have one problem:
When I equip a kit, which is frequently as an Engineer, the art from the back piece disappears. Now I know for a fact that my Fractal Capacitor doesn’t do that, and if I keep the Kit on while I un-equip the Spinal Blades and then subsequently re-equip them, the art stays on along with the kit (and looks absolutely amazing imho).
The reason I spent the time to get this piece was that I hoped for a beautiful back piece that I could show off while tossing Grenades/Bombs at everything in the universe. Any hope for a fix to this?
