>no precision
hitting it with your hand
>some precision
affix a blade using twine or sap or some such
>more precision
develop something to bind it more strongly - like wedging it into a crevice
>more precision
create something fixed sufficiently that you can get a repeated shape
>more precision
make a repeated shape that allows you to construct something that lets you affix things into a stonger position
>more precision
develop unrelated technologies, like blacksmithing, that let you make things more precise by using better materials
>more precision
create a machine that can generate reasonably precise cuts repeatedly
>more precision
Make something more precise than that
>more precision
make something more... you get it
rock in hand = rough
rock attached to other rock = less rough
metal attached to metal = fine
it just goes progressively. We are continuously breaking records of precision even to this day.

If we use precision machining to machine components for precision machining machines, then how did we build the first precision machining machine…
