Many flake tools, or modified debitage don't show lots of flake scars. I don't believe for a minute that everybody was nor needed to be, an expert knapper. Most folks could shape tools and knap out an edge to varying degrees, but not everyone could flake out a nice point or tool. Imo.
Many flake tools don't show flake scars? Yes, virtually all of them do, isn't that why your refer to them as flaked tools? Modified debitage not so much, after all, a simple flake makes a great knife all by itself. Then again, if it's modified it's going to show that in terms of secondary flaking... and even if it's not intentionally modified, it will be modified by use because most flakes flatten out to a super thin cutting edge which is great if you're cleaning a rabbit for dinner but by doing that the super thin edge, under close inspection, will have many many tiny flakes on it that popped off just by applying pressure while cutting through the skin/flesh or whatever it was used for. I don't think they were all expert knappers either bean, that's not my point (no pun intended

) My point is this, whether your the best knapper in the tribe or the worst one doesn't matter, if you make a tool or point you're still going to modify it to some degree and leave evidence of that in most cases. This rock shown in the pic is nothing more than a broken rock from the looks of it. There are no flaking scars that can be seen, no flaking ridges, nothing but your imagination here again as evidence. Not to get off topic too far here but I have to elaborate on that whole thing about them not all being experts: There can be no doubt that some were better than others but if your entire way of life depends to some degree on your ability to make tools it's a pretty safe bet that you're going to get fairly good at it. Certainly one would get good enough at it that their attempt to make a tool would be easily distinguishable in most cases from an ordinary broken rock.
When I was a boy I found an old dump out in the woods with tons of old broken jugs and bottles. This is where I first learned to knapp....even my very first attempts, with no guidance, yielded ugly crude tools covered in flaking scars. I never did use all the glass in that old dump, and to this day there is still lots and lots of broken jugs and bottles. The beanman of the future will pick up some of those broken bottles and say "Look!! I think this is a knife, see, it's sharp on one side and has a flat spot for a thumb." even though what he picks up was broken by throwing it there in the first place and never actually knapped at all.
