Actually I was thinking more along the lines of the sword you gave in your example photo. I like the design and look of that sword. Also, I'd like it to have 'true' edges, like a normal sword has, and for the obsidian to be more 'worked' than be in its natural or primitive form. What I mean in a nutshell is make it look like a normal sword, and just and have the obsidian (not the actual edges, or the the the true blades themselves) colored dark to simulate the color of obsidian.
I hope this helps.
