Well, they say," Beauty is in the eye of the beholder", I guess it depends on who the holder is!
First, I would say to anyone that you have to please yourself first. then your customer or in this case your friend is the only other opinion that should matter, as makers we are the ones that come up with the original idea and the end result, at some point along the build you had to think it was looking good, then ran into the flow issue. So ask yourself, "what were you thinking?" Seriously, answer yourself first, then decide how the best way to make it flow for its intended purpose.
My opinion on the flow would be to first to look at the ergonomics, since we can't see all aspects and feel it in hand you'll have to decide how it feels, I always handle my knives and use them in there intended purpose if it is a handle design that I haven't used before, I look for hot spots first, secondly I feel for grip issues. The purpose of this knife is to be a utility knife, basically a "no frills" sorta blade, if that's the case and there are no problems with the handle and your friend likes it as is, I say let it go. Personally I say it looks pretty good, the blade looks to be about 3" or so, it may need a little better junction between the handle and the guard area, I guess if there was a little arc there or more curvature, it may give it more flow. There are curves all over this design, except in the area I mentioned. Hope this helps, Rex
