Ding ding ding! Two points! Right on both accounts.... I'm not sure if I'm set on that center color/grain, but I'm either gonna do tungsten or titanium for the shank... Partially because it looks cool, and partially because I will scratch the hell out of anything softer. Anything I should look for? I have about a year....
There are benefits and negatives to both metals. I'll take this to PMs to avoid hyjacking the original thread.
