The answer is in the question. *yep*

The nth degree, is the nth degree, and while one chases this degree, they will never attain it, as humans simply cannot grasp the concept. If in theory they did, they would not know how to carry on with "life" as we humans define "life".
The reality is, everything has been discovered, just humans re-discover it.
The answer is in the question.
Why does a hand engraver not put a polished edge on a graver?
How come a butcher can break down more boxes in the freezer area than in the room temperature area with the same knife?
Why does a seasoned fisherman get more fish cut in the North Atlantic than he /she does in a Tropical setting?
How come the sharpest shave a barber gives, is that first shave, from a razor, that sat over the Sunday and Monday he was closed and that razor sat in a glass box with a Tuberculosis light, [UV] and he did not strop it before shaving with it ?
Diamonds have the greatest refraction of light of any gemstone, how are they cut and polished?
Which type of cut presents the best refraction of light and allows the diamond to give off what it does - to the best of "human" ability now.
Why does a scalpel stay sharper in a Operation Room Theatre, than if used in room temperature?
Hint: There ain't no nth, there are degrees for tools for tasks that work best .
Hint II.
Find a old seasoned hand engraver, and look at his/her gravers, sharpened by hand. Look at a 44 Flat, and ask yourself if it does not remind one of a Razel.
Do not look at the 44 Flat sharpened using a Doo-Dad.
The key is in the 44 Flat sharpened by hand.
