I think the only makers who have managed to reproduce a Kephart somewhat correctly are ones who have actually had the opportunity to handle an original. As simple as the knife looks, there are a lot of design elements and subtleties that get overlooked if one is simply going off of pictures.
Even with Ethan Becker, the Kephart held no appeal for him until he actually had the opportunity to handle one in person.
I am thrilled with your approach though, there is something to be said for modern manufacturing and design. Though the likelihood of me getting to experience an original is slim to none, I do have a custom Kephart being made (the maker having had the above opportunity), I have yours in the works (IIRC, you also had that opportunity), and I have a number of production examples (Ka-bar and others). Once they are all in hand, I will be doing an extensive study - utilizing Kephart's philosophies and demonstrating how they all comparatively perform.
I am really looking forward to it.
