Making the Micro Bevel Too Large
The purpose of a micro bevel is to reinforce the apex—not to replace the main edge bevel.
Using a Much Higher Angle
Increasing the angle too much creates a new edge rather than a true micro bevel.
A small increase is usually all that's needed.
Adding a Micro Bevel to Every Knife
Not every knife benefits from one.
Many kitchen knives and light-duty folders perform exceptionally well with only a properly sharpened edge bevel.
Skipping the Main Edge
A micro bevel cannot compensate for an edge that has not been fully apexed.
Always establish the main edge before adding a micro bevel.
