Why don’t they just cultivate the art of sharpness already? ?

Cultivate the art of a brick in a sock.

Unfortunately sharpness is measurable and has a limit. Let a just say for some thing to be truly sharp it has to have that mono molecular edge. But the edge isn't the issue it pushing the rest or the blade through the split the mono molecular edge made, also how do yo go beyond that:⁷ neutron edge, muon edge or quark edge what lies beyond could you have a blade that induces a Bose-Einstein condensate of objects it passes through. The whole qi intent stuff is just bs to make it seam like a higher tier. It's not and doesn't have to be, at the end of the its lazy writing to make a point x is better then y, that's it really.

The best edge is to have no edge. Split space and everything will slide apart.

I don't know what to say at this point but they all lead to destruction at an atomic level and at this point the character could make something or someone disintegrate with just his thought he is basically OP

Although it depends on the narrative and on what the writer wants, I think one of the reasons the weapon or the "idea of the weapon" is cultivated is partly because of the philosophy(?) and concept it or the user represents. Like for the sword (the standard ones) = chivalry, gentlemanly, being upright, scholarly, etc. Saber = fierce, frank, straightforward, barbaric, rough, etc.
I don't really take this tropes to seriously when reading CN Cultivation novels since they're only relevant for the first 200 out of 3000 chapters.
