that's a really pertinent question David, and I'm not sure yet how to answer it, but I'll take a quick stab at it.
I'll tell you, the design process happened over quite a long course of time, and I had lots of time to consider Nick's reinterpretation of my original design. I even spent some time reinterpreting his reinterpretation, and among other small things, removed the recessed ricasso altogether. Eventually, though, Nick's version became the knife which was one of the fruits of this thread.
Y'know, there came a point in time where I could really have pushed to have Nick try harder to stay true to the original design, but I realized that in pushing him to do that, I'd be pushing him to not be true to himself.
Nick has his own take on life, the world, and all that, and he's brilliant. Possibly a genius. Who am I to dictate what he brings to life in this world? I wasn't so tied to my design. If I was, I'd probably have either tried to make it myself or got someone to make it quickly. I was tied to Nick, as my knifemaker, and I forever will be, so long as he continues making knives, I will try my hardest to be his patron.
With Nick, and so many other things, good things come to those who wait Allowing him free reign to interpret my wishes resulted in a knife which far surpassed them.
Here's a link to a discussion that occurred regarding design;

Nick also posted a thread somewhere in this forum talking about our designing process that was extremely interesting, (I thought so, anyway).
