>1) Youve clearly nver tried to create a sharp cutting rock. Rocks split, are of varying consistency.

Sure. So just split a few until you get one. I used to do this often as a kid. I wasn't old enough to have a pocketknife like my friends did, but of course I wanted to pay "Indian" or whatever just like they did. I literally just thew rocks against each other on the ground. Sometimes you get a nice edge, sometimes you don't. But it's not hard to get something that's sharp and could cut something. I'm just talking about making a sharp edge, not knapping an elaborate flint knife.

>2) Ask yourself how far off dogs or cats are from developing and making a knife, then return to me about cognitive difficulty.

I literally have no idea why you're talking about dogs and cats. We're talking about human beings here.

>3) Sharks have sharp, saw edged cutting teeth.
Some do, some don't. Any many fish other than sharks have sharp edged teeth. See pic related. The teeth on the upper jaw could easily cut you if you handled it carelessly.

>>I cant think of even one mammal that has cutting edges on its teeth
Ever seen a boar's tusks? They are literally knife-sharp from rubbing against each other.

>4) Bone knives are very dulll and soft, and you require a very large bone to make one.
Sure. But they're still a cutting tool.

>5) A rock or a stick needs no modification. Cutting edges need attention and deliberate purpose to create.
Agreed. But that "attention" and "purpose" isn't very significant.
