**Last Comment Edit** When I said I own something like this, I definitely did not mean the design, I simply meant a hair pin in general. Sorry if I freaked you out at all! Realized how bad it sounded after I hit "add comment."
The problem isn't background color. I've played with it a bit, and the problem is the way the camera catches the translucence of the brown color. It's seeing a quality that isn't visible in person because of how the sensor collects light. Nothing much I can do about it, I'm afraid.
You could note me to discuss the idea. I -might- just know someone who could get me such a blade to work on. And I've been wanting to try etching on steel. A carved handle, or perhaps something like a curvy black horn from one of the smaller african antelope species?
