How was it created

This is a couple of pieces that seemed to be carved one is the eagle head i circled and other carving is around the eye!. How did they create this? Whst tools? How long?  
These are questions i wonder about. I find some very small “chips” that actually fit in between thumb and index fingers perfevtly but they leave a timy tip out !  that is sometimes very shiny and to me it is pisdibly a precision tool. Not the trash that i am told by experts! But since art is in my imsgination no tools to creste ut exist!  Anyone think about the way the art was created also!!
Thx
Judy

There are 5 documented types of working in flint, pressure, percussion, drilling, polishing and Qu??? ( I forget its name) which involves removing layers. As for the scratches, I am unsure, perhaps diamonds as mentioned in another post. Another theory I have is the application of heat, and sheet ice which is totally untested/unsupported. As for some of the flake removals in my finds, I just do not know, the precision in which large single flakes are removed without bulbs of percussion is a mystery.

Sometimes natural inclusions/features in the flint are exploited also....

Ooooh! There's a little astronaut at the bottom of your 2nd photo Judy.

Nice stone!

That cloaked figure is a giveaway for spotting these finds, looks quite sinister as the top half figure with sleeve and hand pointing downwards.

It appears to be a shaman motif. Note the hat and chin beard.

I see something like this except with sleeve and hand pointing downwards.
