Jeff,
You have it now. I've been watching you get the guard more forward and now you have it. The radius is perfect and I like the slight formation of the finger notch. Joe Keeslar does'nt do the notch much from what I've seen.
I know that you are not neccesarily imitating Joe Keeslar's work exactly, but he does one more little touch that I think you may want to experiment with. He gives the sides of the guard a very slight radius and he does it with the hammer. In other words, while forming the basic radius that shows in the profile, he tilts his hammer to the right and then to the left forging the curl of material forward and upward. The radius goes two ways.
I dont mean to get off subject. I like this style of knife. By the way, you have pretty hands in the other thread.
