The Oakedge sounds very nice. I've never a fancy work knife with file worked backspring and blade, so I don't know if the file work on the blade spine acts like jimping.
It does give a place the rest the thumb, and it certainly catches the eye. From what I have seen of the process on line, it requires quite a bit if skill and extra finish work. I am impressed that Oakedge can offer it as an option for such a reasonable cost.
