Holy hell, I don't even know where to start. Your last one was awesome, but this one is out of this world. I know what I go through when I'm casting segments for my 'Segmacasts', which you don't see a lot of for a reason. That's just too dang much work! To get the patterns you have, using the methods that I use, that must have taken a good bit of prep-gluing. You've taken 'Eagle-level' precision and brought it into the casting world. I can't wait to see what you come up with next!
The only reason that I'm not worried about you selling those blanks is that I'm pretty sure that I can make a dozen of mine in the time it takes to make one of yours, and you're going to have to charge accordingly to keep from doing it for free! Keep it up, man! You definitely have the gift of patience.
I love that pen! Next on your list of things to do is to make a 6" long one and send it to me for a review on the ability to turn it into a two-blank, multi-diameter, closed-end pen while matching up the lines across the center band, right? [
