A variation on a theme for me lately, this one is a commission. I used a 10mm x 9mm carbon fiber tube, tellurium copper, and a Schmidt SKM88 mechanism. The clip was originally chrome, I electroplated with copper sulfate and a 1.5 volt DC current. It didn't work at first until I figured out it had a clear coat applied. After stripping and buffing it plated quickly. Hope you like it. I'm about done working with copper, it wants to scratch just looking at it sitting on the bench.
