I prefer a flush hang. I think the first proud handles I saw were European. Then a bunch of guys on websites started hanging everything proud. I thought it was just a fast way to hang a handle, less hand fitting. Leave some wood sticking through and put a fat wedge in it to spread the wood. I have a couple axes pushing 100 years old with flush hangs that are still tight and serviceable. I like the old video from the Forest Service, he hangs all of his flush. I think it might have been the first version of the same guy that was in print, and he said never drive a steel wedge cross ways, only in line with the kerf. But, I think he said that was a strength issue, not a tightness issue. I'd have to look up the old print version and re read it. The double that Multifaceted hung for me was a little proud and looks Very Nice. Some of the ones you see, on line, look like they just grind the handle down till it sticks through loose. Leave an inch of wood sticking through and wedge it so far the wood bends and makes a pressure fit, instead of hand fitting for a tight friction fit. I don't like them at all.
