Here are a couple Sierras with platinum/black titanium. The first one is deer antler and the second one is made from water main pipe. I'm not sure I chose the correct plating for the antler, but I like it with the blue.
I thought it was the picture but from your comment maybe not. I think the antler and the kit don't show enough contrast, but again might be picture. The blue does look like a retro 50's color. Both pens are good work.
Guess I'm the odd man out because I liked the way the titanium looked with the antler. It's not a strong contrast but it lets very clean lines. I guess the main thing is that the person who ends up with it likes them together []
Those two Sierra kits are very clean looking. I really like them! The antler pens looks great as you have some nice coloring at the top. The watermain pen is sweet too!![] Your pictures are great!!!
