I have never held a regulator handle, but I am sure it feels great in hand. I guess the layout of the knife, 611 being more straight than the others, the regulator handle suits it better. The basic handle calls for a bit of a curve on the tang, I think...

Maybe I am just being difficult, (or "Rasmus modsat" in Danish) because I don't have a Scrapper 6, and want something close to that.
